Greetings!

"Solve for x: 7x-4+x=12"...

Add like terms.
8x-4=12
Add 4 to both sides.
(8x-4)+4=(12)+4
Simplify.
8x=16
Divide both sides by 8.
(8x)/8=(16)/8
Simplify.
x=2

The variable is equal to 2.

Hope this helps.

Enter the value of b that makes the statement true: 5xb is less than 5 but greater than 0.
AlexFokin [52]
0<5xb<5  divide all terms by 5

0<xb<1  divide all terms by x

0<b<x

If you meant 5b as in 5*b then:

0<5b<5  divide all terms by 5

0<b<1

b is infinitely many values between 0 and 1.
