Question

Solve the equation in the image (yr 8 maths, 50pts)

Answer 1

Answer: x = 4

Explanation:

Given equation

4x - 20 = -x

Add x on both sides

4x - 20 + x = -x + x

5x - 20 = 0

Add 20 on both sides

5x - 20 + 20 = 0 + 20

5x = 20

Divide 5 on both sides

5x / 5 = 20 / 5

`\Large\boxed{x=4}`

Hope this helps!! :)
