Question

How do you solve 18−(2a−5)−2(a+2)=3a+5?

Answer 1

Hope this helps

Simplifying the above equation,

a=2

Answer 2

Answer: a=2

Step-by-step explanation:

Simplify both sides of the equation.

18−(2a−5)−2(a+2)=3a+5

18+−2a+5+(−2)(a)+(−2)

(2)=3a+5(Distribute)

18+−2a+5+−2a+−4=3a+5

(−2a+−2a)+(18+5+−4)=3a+5(Combine Like Terms)

−4a+19=3a+5

−4a+19=3a+5

Subtract 3a from both sides.

−4a+19−3a=3a+5−3a

−7a+19=5

Subtract 19 from both sides.

−7a+19−19=5−19

−7a=−14

Divide both sides by -7.

−7a −14

----- = ------

−7 −7

a =2
