Step-by-step explanation:
To solve the following equations, we need to isolate the variable asked using inverse operations to solve equations.
Remember that addition and subtraction are inverse operations, as multiplication and division.
Therefore,

Question is:
Fill in the blanks to solve

Answer:

Step-by-step explanation:
Given

Solve
Multiply both sides by x


Make x the subject


Rx - sx + y = b
WHEN SOLVING FOR X :
rx - sx + y = b
We must get x onto it's own side, so subtract y from both side.s
rx - sx = b - y
Then, factor out x.
x(r - s) = b - y
Then, divide both sides by (r - s).
x(r - s) ÷ (r - s) = b - y ÷ (r - s)
Simplify.
x = b - y / r - s →

WHEN SOLVING FOR Y :
rx - sx + y = b
We need to isolate y, so get rid of everything BUT y on the left side.
Subtract rx from both sides.
-sx + y = b - rx
Then, add sx to both sides.
y = b - rx + sx
