Answer 2

1) 13x = 195 To solve this equation, we need to isolate the variable x. We can do this by dividing both sides of the equation by 13: 13x/13 = 195/13 x = 15

2) x + 18 = 468 To solve this equation, we need to isolate the variable x. We can do this by subtracting 18 from both sides of the equation: x + 18 - 18 = 468 - 18 x = 450

3) 11x + 6x = 408 To solve this equation, we need to combine like terms on the left side of the equation: 17x = 408 Next, we isolate the variable x by dividing both sides of the equation by 17: 17x/17 = 408/17 x = 24

4) y + 27y = 952 To solve this equation, we need to combine like terms on the left side of the equation: 28y = 952 Next, we isolate the variable y by dividing both sides of the equation by 28: 28y/28 = 952/28 y = 34

5) x/19 = 26 To solve this equation, we need to isolate the variable x. We can do this by multiplying both sides of the equation by 19: (x/19) * 19 = 26 * 19 x = 494

6) 476 / x = 14 To solve this equation, we need to isolate the variable x. We can do this by multiplying both sides of the equation by x: (476 / x) * x = 14 * x 476 = 14x Next, we isolate the variable x by dividing both sides of the equation by 14: 476/14 = 14x/14 34 = x

1) 19x = 95 To solve this equation, we need to isolate the variable x. We can do this by dividing both sides of the equation by 19: 19x/19 = 95/19 x = 5

2) x + 22 = 132 To solve this equation, we need to isolate the variable x. We can do this by subtracting 22 from both sides of the equation: x + 22 - 22 = 132 - 22 x = 110

3) 38x - 16x = 1474 To solve this equation, we need to combine like terms on the left side of the equation: 22x = 1474 Next, we isolate the variable x by dividing both sides of the equation by 22: 22x/22 = 1474/22 x = 67

4) y + 27y = 952 To solve this equation, we need to combine like terms on the left side of the equation: 28y = 952 Next, we isolate the variable y by dividing both sides of the equation by 28: 28y/28 = 952/28 y = 34

5) x/25 = 16 To solve this equation, we need to isolate the variable x. We can do this by multiplying both sides of the equation by 25: (x/25) * 25 = 16 * 25 x = 400

6) 324 / x = 27 To solve this equation, we need to isolate the variable x. We can do this by multiplying both sides of the equation by x: (324 / x) * x = 27 * x 324 = 27x Next, we isolate the variable x by dividing both sides of the equation by 27: 324/27 = 27x/27 12 = x
