# How do you solve 10b + 18= 8b + 4?

Mar 27, 2018

$b = - 7$

#### Explanation:

Step 1: Subtract 8b from both sides.

10b+18−color(blue)(8b)=8b+4−color(blue)(8b)

$2 b + 18 = 4$

Step 2: Subtract 18 from both sides.

2b+18−color(green)(18)=4−color(green)(18)

2b=−14

Step 3: Divide both sides by 2.

(cancel2b)/cancelcolor(orange)(2)=(−14)/color(orange)(2)

b=−7
