To solve 7-2a-5-14=-2+3a :

1) combine like terms: 7-19 - 2a = -2 + 3a, and then -10 = 5a

2) solve this equation for a: a = -10/5 = -2.

The solution of 7-2a-5-14=-2+3a is a = -2.

7 - 2a - 5 - 14 = -2 + 3a

Firstly, collect like terms (the constants) on the left side of the equation.

7 - 5 - 14 = -12

The equation becomes

-12 - 2a = -2 + 3a

Add 2 to both sides. The -2 on the right side cancels out and the constant -12 on the left becomes -10.

-10 - 2a = 3a

Add 2a to both sides. The -2a on the left cancels out and the 3a on the right becomes 5a.

-10 = 5a

Divide both sides by 5. The coefficient on the right cancels out and the -10 becomes -2.

-2 = a

Answer:

a = -2
