Answer:
18
Step-by-step explanation:
We are to determine the value of a
to do this we have to make a the subject of the formula. this can be achieved by taking the following steps
divide both sides of the equation - 2(42 - a) = 48 - by 2
42 - a = 24
take a to the right hand side and bring 24 to the left hand side
a = 42 - 24
a = 18
