Question

Solve for x
3(5x + 4) - 20 - 13x = -4

Answer 1

3(5x + 4) - 20 - 13x = -4
first use the distributive property with 3(5x + 4)

15x+12-20-13x=-4
combine like terms

2x-8=-4
add 8 to both sides

2x=4
divide both sides by 2

x=2

Answer 2

3(5x+4)- 20 - 13x=-4
expand:
(3×5x) + (3×4) - 20 - 13x=-4
15x + 20 - 20 - 13x = -4
simplify:
15x - 13x + 20 - 20=-4
2x=-4
solve:
2x/2=-4/2
x=-2
