Question

2c +10 = 30
How can I solve this?

Answer 1

10

Explanation:

2c + 10 = 30

so we take 10 to the other side to become - 10.

Therefore 2c = 30 - 10

= 20

Divide both sides by the coefficient of c that's 2

2c = 20

c = 10

Answer 2

Explanation:

2c+10=30

2c+10−10=30−10

2c=20

2c÷2=20÷2

Answer: c=10
