Answer:

x = 3

Step-by-step explanation:

Step 1 - Expand the brackets:

-2(1 - 5x) = 4 - 4(-2x)

-2 - (-5x) = 4 - (-8x)

-2 + 10x = 4 + 8x

Step 2 - Subtract 8x from both sides:

-2 + 10x - 8x = 4 + 8x - 8x

-2 + 2x = 4

Step 3 - Add 2 to both sides and isolate 2x:

-2 + 2x + 2 = 4 + 2

2x = 6

Step 4 - Divide by two:

2x ÷ 2 = 6 ÷ 2

x = 3

Hope this helps!
