2

Explanation:

-2 (1-4x) = 3x + 8

-2 × 1 - -2 × 4x = 3x + 8

-2 + 8x = 3x + 8

8x - 3x = 8 + 2

5x = 10

x = 10/5

x = 2

hope this helps you!

Answer 2

x = 2

Explanation:

`-2 (1-4x) = 3x + 8\\\\Expand\: -2(1-4x) \: :-2+8x\\-2+8x=3x+8\\\\\mathrm{Add\:}2\mathrm{\:to\:both\:sides}\\-2+8x+2=3x+8+2\\\\Simplify\\8x=3x+10\\\\\mathrm{Subtract\:}3x\mathrm{\:from\:both\:sides}\\8x-3x=3x+10-3x\\\\Simplify\\5x =10\\\\\mathrm{Divide\:both\:sides\:by\:}5\\(5x)/(5)=(10)/(5)\\\\Simplify\\\\x =2`
