Answer:

Simplifying

ax + -1by = 8

Solving

ax + -1by = 8

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add 'by' to each side of the equation.

ax + -1by + by = 8 + by

Combine like terms: -1by + by = 0

ax + 0 = 8 + by

ax = 8 + by

Divide each side by 'x'.

a = 8x-1 + bx-1y

Simplifying

a = 8x-1 + bx-1y

Reorder the terms:

a = bx-1y + 8x-1 have a nice day

Answer:

[tex]y =\frac{-Ax+8}{B}[/tex]

Step-by-step explanation:

Ax+By=8

Our objective is to solve for y

First step is to subtract ax from both sides

Ax - Ax + By = 8 - Ax

simplify

By = 8 - Ax

Next step is to divide both sides by B

By/B = (8 - Ax) / B

simplify

We get that [tex]y =\frac{8-Ax}{B}[/tex]
