Answer:
-8/5 = x
Step-by-step explanation:
-3(x+4) = 7x + 4
Distribute
-3x-12 = 7x+4
Add 3x to each side
-3x-12+3x = 7x+4+3x
-12 = 10x+4
Subtract 4 from each side
-12-4 = 10x+4-4
-16 = 10x
Divide by 10
-16/10 = 10x/10
-8/5 = x
Answer:
x = [tex]\frac{-8}{5}[/tex] or x = -1.6
Step-by-step explanation:
-3(x+4) = 7x + 4
do the left side first
multiply x by -3 and multiply 4 by -3
you get -3x - 12 = 7x + 4
add 3x to both sides
you now have -12 = 10x + 4
subtract 4 from both sides
you get -16 = 10x
divide each side by 10
you have x = [tex]\frac{-8}{5}[/tex] or x = -1.6
