    Answer:

    a = -6

    Step-by-step explanation:

    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

    at last,

    a = -6

    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

    2

    a=−6
