Solve the formula for h. A=bh

A/b = h

Step-by-step explanation:

A=bh

Divide each side by b

A/b=bh/b

A/b = h

See below.

Step-by-step explanation:

So we have the formula:

And we want to solve it for h.

To do so, divide both sides by b. The right will cancel. Thus:

And we're done!

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
