Write a percent equation that can be used to solve the following problem: 820 is 20% of what number? A. n = 0.2 x 820
B. 820 = 0.2 × n
C. 0.2 = n × 820
D. none of these

i think b is the correct option

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
