solve for y

mx+ny=r

3 answers

To solve for y, we need to isolate it on one side of the equation.

mx + ny = r

We can start by subtracting mx from both sides:

ny = r - mx

Next, divide both sides by n to isolate y:

y = (r - mx)/n

Thus, the solution for y is:

y = (r - mx)/n
P=2(L+W)

Solve for L
To solve for L, we need to isolate it on one side of the equation.

P = 2(L + W)

We can start by dividing both sides by 2:

P/2 = L + W

Next, subtract W from both sides:

P/2 - W = L

Thus, the solution for L is:

L = P/2 - W
