Answer:
Number = -1
Step-by-step explanation:
8 - x = 3(x + 4)
8 - x = 3x + 12 ( /+x / -12 on both sides)
8 - 12 - x + x = 3x + x + 12 - 12
-4 = 4x (/ divide by 4)
-4/4 = 4x/4
-1 = x

Answer:
-2.1
Step-by-step explanation:
We have an equation and the question is asking us to look for x.
To solve, we must isolate x and get it on its own.
2.5(x + 4) = 4.75
Distribute the 2.5 to get rid of the parenthesis :
(2.5(x) + 4(2.5)) = 4.75
2.5x + 10 = 4.75
Subtract ten from both sides :
2.5x = -5.25
Divide 2.5 by both sides to get x alone :
x = -2.1
