Question

20 - 4x = 2(4 - 8x) This needs solving

Answer 1

20 - 4x = 2(4 - 8x)

Make sure to do the parentheses first or factor out first

20 - 4x = 8 - 16x

add 16x to both sides

20 + 12x = 8

Subtract 20

12x = -12

Divide by 8

x = -1

Answer 2

Answer:

x=-4

Step-by-step explanation:

20-4x=4-8x

move variable to the left side and change its sign:

20-4x+8x=4

-4x+8x=4-20

4x=4-20

4x=-16-Divide both sides of the equation by 4

x=-4
