Question

solve for y.

y - x = 15
x = 12
simplify your answer as much as possible.

Explanation:

Step1: Substitute x=12 into equation

Substitute $x=12$ into $y-x=15$:
$y - 12 = 15$

Step2: Isolate y by adding 12

Add 12 to both sides:
$y = 15 + 12$

Step3: Calculate the sum

Compute the right-hand side:
$y = 27$

Answer:

$y=27$
