Answer for 5x+3x=420

Step 1: Simplify both sides of the equation.

5x+3x=420

(5x+3x)=420(Combine Like Terms)

8x=420

8x=420

Step 2: Divide both sides by 8.

$\frac{8x}{8}$ = $\frac{420}{8}$

x = $\frac{105}{2}$

Answer for 12x+9=1080

Step 1: Subtract 9 from both sides.

12x+9−9=1080−9

12x=1071

Step 2: Divide both sides by 12.

$\frac{12x}{12}$ = $\frac{1071}{12}$

x = $\frac{357}{4}$
