Answer:
y = 75
Explanation:
23 + y - 19 = 79
We are to solve for y.
To solve for y, we are to follow the step below
23 + y - 19 = 79
subtract nineteen from twenty three
y + 4 = 79
Subtract four(4) from both-side of the equation
y + 4 - 4 = 79 - 4
On the left hand-side of the equation, 4-4=0 leaving us with just y
y = 79 - 4
y =75
Therefore y = 75
