How do you solve

x/a - 1 = y/b for y?

Algebra question I'm stuck on.

Thanks!

multiply each term by ab, the LCD

bx - ab = ay
y = (bx - ab)/a

or

just multiply both sides by b
bx/a - b = y , which is the same as my first result

Thank you so much Reiny!

What is the least common denominator?

what the least common denominator is a right?

To solve the equation for y, we need to isolate the y variable.

Given the equation: x/a - 1 = y/b

Step 1: Start by multiplying both sides of the equation by b to eliminate the fraction:
b * (x/a - 1) = y

Step 2: Distribute b to both terms within the parentheses:
(b * x/a) - (b * 1) = y

Step 3: Simplify:
(bx/a) - b = y

Therefore, the equation is simplified to y = (bx/a) - b.

To recap, to solve for y in the equation x/a - 1 = y/b, we multiplied both sides of the equation by b and simplified to obtain the final solution y = (bx/a) - b.
