Question

5х+3х-8=16 6y+20-y=35 4х-6=2х

Answer 1

$5x+3x-8=16\\8x-8=16\\8x=16+8\\8x=24\\x=24:8\\x=3$ Ответ: 3.

$6y+20-y=35\\5y+20=35\\5y=35-20\\5y=15\\y=15:5\\y=3$ Ответ: 3.

$4x-6=2x\\4x-2x=6\\2x=6\\x=6:2\\x=3$ Ответ: 3.

Answer 2

Let's solve the equations step by step:

1. 5x + 3x - 8 = 16 Combine the x terms on the left side: 8x - 8 = 16 Now, isolate the x term: 8x = 16 + 8 8x = 24 Finally, divide by 8 to find the value of x: x = 24 / 8 x = 3

2. 6y + 20 - y = 35 Combine the y terms on the left side: 6y - y + 20 = 35 Simplify the left side: 5y + 20 = 35 Now, isolate the y term: 5y = 35 - 20 5y = 15 Finally, divide by 5 to find the value of y: y = 15 / 5 y = 3

3. 4x - 6 = 2x Subtract 2x from both sides to combine x terms on the left side: 4x - 2x - 6 = 0 Now, simplify the left side: 2x - 6 = 0 Add 6 to both sides to isolate the x term: 2x = 6 Finally, divide by 2 to find the value of x: x = 6 / 2 x = 3

So, the solutions to the equations are: x = 3 y = 3
