Solving Formulas for a Given Variable

ax+r=7
solve for r

• r=7/ax
• r=7-ax
• r=7+ax
• r=7ax

Solve for a.

• a = pw
• a = p/w
• a = w/p
• a = w + p

Solve for y:
8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

IR = V
(solve for R) 

• R = IV
• R = ^I/_V
• R = ^V/_I
• R = V - I
