Question

1)12х-35+7х=98 2)25(х+1)-16=59

Answer 1

1)12х-35+7х=98
   19х=133
   х=133÷19
   х=7


2)25(х+1)-16=59
   25х+25-16=59
   25х+9=59
   25х=50
   х=50÷25
   х=2

Answer 2

(12-35+7)x=98
-14x=98
x=98:-14
x=7
во втором сомневаюсь)

Answer 3

1. To solve the equation 12х - 35 + 7х = 98, we first combine like terms on the left-hand side of the equation to get:

19х - 35 = 98

Next, we isolate the variable term (19х) by adding 35 to both sides of the equation:

19х = 133

Finally, we solve for x by dividing both sides of the equation by 19:

x = 7

Therefore, the solution to the equation 12х - 35 + 7х = 98 is x = 7.

2. To solve the equation 25(х + 1) - 16 = 59, we first simplify the left-hand side of the equation by distributing the 25:

25х + 25 - 16 = 59

Next, we combine like terms on the left-hand side of the equation:

25х + 9 = 59

Then, we isolate the variable term (25х) by subtracting 9 from both sides of the equation:

25х = 50

Finally, we solve for x by dividing both sides of the equation by 25:

x = 2

Therefore, the solution to the equation 25(х + 1) - 16 = 59 is x = 2.
