Answer
-6
Step-by-step explanation:
2(23+a)=34
(2)(23)+(2)(a)=34(Distribute)
46+2a=34
2a+46=34
Step 2: Subtract 46 from both sides.
2a+46−46=34−46
2a=−12
Step 3: Divide both sides by 2.
2a
2
=
−12
a=−6
Answer:
a = -6
2(23 + a) = 34,
multiply the 2 into the bracket of (23 + a)
then it will become,
46 + 2a = 34
shift the numbers with unknown to one side,
2a = 34 — 46
so,
a = -12/2
