Question

Can someone help me with this

Answer 1

x = 5

Explanation:

Given

2x + 10 = 20

Subtract 10 to both sides

(2x + 10) -10 = 20 - 10

2x = 10

Divide both sides by 2

`(2x)/(2) =(10)/(2)`

x=5

Check your work. Substituted 5 for x

2x + 10 = 20

2(5) + 10 =20

10 + 10 = 20

20 = 20

Answer 2

x=5

Explanation:

2x+10=20

-10 -10

2x=10

then divide both sides by 2

x=5
