Question

8[4-x]=7x+2 Solve the equation

Answer 1

Answer:

x=2

Step-by-step explanation:

8x4=32

-x x8=-8x

32-8x=7x+2

+8x on both sides

32=15x+2

32-2=30

30=15x

divided by 2

2=x

Answer 2

Answer:

2$\frac{4}{15}$

Step-by-step explanation:

First factor our the (4-x):  (8*4)(8*x)
Then we have 36 - 8x = 7x + 2

Isolate the x:

32 -2 = 8x + 7x

Simplify both sides:

30 = 15x

Divide both sides by 15

$\frac{30}{15}$ = $\frac{15x}{15}$

Simplify further if necessary:

x = 2
