Answer:

a = −6

Step-by-step explanation:

Step 1: You should divide both sides by 2.

[tex]23+a=\frac{34}{2}[/tex]

Step 2: then simplify [tex]\frac{34}{2}[/tex] into 17.

23 + a = 17

Step 3: next, you need to subtract 23 from both sides.

a = 17 − 23

Step 4: lastly, Simplify 17 − 23 to −6 and you're done!

a = −6

Answer:

a = -6

Step-by-step explanation:

2 (23 + a) = 34

46 + 2a = 34

2a = 34 - 46

2a = - 12

a = - 12/2

a = - 6
