Question

Solve the equation.
30- (x + 5) = 7x-7
The solution is x =

Answer 1

X=4
30-x+5=7x-7
25-x=7x-7
-x+25=7x-7
-x=7x-32
(subtract 7x from both sides)
-8x=-32
(divide by -8) (remember negative times negative= positive)
X=4

Answer 2

`- 30(x + 5) = 7x - 7 \\ - 30x - 150 = 7x - 7 \\ 7x + 30x = - 150 + 7 \\ 37x = - 143 \\ x = ( - 143)/(37) \\ x = - 3.864`

________o____o_____

30–(x+5)=7x-7

30 – x–5 =7x -7

7x+x = 30-5+7

8x = 32

x= 32/8

x=4
