x=2

Explanation:

2x+14+x=20

3x+14=20

3x=6

Then divide both sides by 3

x=2

x=2

Explanation:

Apply the distributive property

2x+2*7+x=20

Multiply by 7 to get 14

2x+14+x=20

Add 2x and x to get 3x

3x+14=20

Since 14 does not contain the variable to solve for, move it to the right side of the equation by subtracting 14 from both sides.

3x=-14+20

Add -14+20 to get 6

3x=6

Divide each term by 3 and simplify.

Answer : x=2
