What should we do first to solve for x?

y=mx+b

• Add b

• Subtract b

• Multiply m

• Divide by m

Solve:
y = mx + b , for b

• y - mx = b
• y + mx = b
• y/mx = b
• y + mx = -b

Solve:

8x + 4y = 16 , for y

• y = -2x + 4

• y = 2x - 4

• y = 2x + 4

• y = -2x - 4

Solve for a.

• a = pw
• a = p/w
• a = w/p

Solve the formula P = 2L + 2W for W.

• $\frac{P-2L}{2}\ =\ W$

• $\frac{P-2W}{2}\ =\ L$

• $\frac{P-L}{2}\ =\ W$

• $\frac{P-W}{2}=L\$

Solve for R:

IR = V

• R = IV

• R = ^I/_V

• R = ^V/_I

• R = V - I

Solve:
C = 2πr, for r
