Question

How to solve 10+2x=100

Answer 1

x=45

Explanation:

First, subtract 10 from both sides of the equation.

10+2x-10=100-10

100-10=90

Next, divide 2 from both sides of the equation.

2x=90

2x/2=90/2

Finally, solve this problem.

90/2=45

x=45, which is our answer.

Answer 2

x = 45

Explanation:

10+2x=100

Subtract 10 from each side

10-10+2x=100-10

2x = 90

Divide each side by 2

2x/2 =90/2

x = 45
