Answer:
13 is your answer for variable a.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable (a).
First, add 22 and subtract 3a from both sides
4 (+22) + 3a (-3a) = -22 (+22) + a (-3a)
4 + 22 = a - 3a
Simplify. Combine like terms
4 + 22 = a - 3a
26 = 2a
Isolate the variable (a). Divide 2 from both sides
(26)/2 = (2a)/2
a = 26/2
a = 13
13 is your answer for variable a.
