Exact Form:

x=92x=92

Decimal Form:

x=4.5x=4.5

Mixed Number Form:

x=412x=412

Answer 2

the answer is x = 9/2

explanation

3 (x - 2) = 7 – (4 - x)

apply the distributive law to 3(x - 2)

to get 3x - 6

simplify 7-(4-x)

3 + x

you now have

3x - 6 = x + 3

add 6 to both sides

-6+6=0   3 + 6 = 9

3x=x+9

subtract x from both sides

3x - x = 2x     x - x = 0

2x = 9

divide both sides by 2

2x/2 = x    9/2

to get x = 9/2
