Guided Practice for Solving Equations

Solve: 14m²-12m = 0

• m=2 and m=76

• m=2 and m=0

• m=14 and m=12

• m=0 and m=6/7

Solve the formula for r.   What is the 1st step?

• Divide each side by t. 

• Subtract t from each side. 

• Add t to each side. 

• Multiply each side by t. 

Solve m - n = 5 for m.

• m = 5 + n

• m = -5 - n

• m = -5 + n

• m = 5 - n

Solve for a.

• a = pw

• a = p/w

• a = w/p

• a = w + p

What is the first step (after setting up your workspace) to complete when solving this equation?
10 - 3y = 4

• Add 10

• Subtract 10

• Add 3

• Divide by -3

What is the first step (after setting up your workspace) in solving this equation:
5x + 7 = 12

• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

Solve:
y = mx + b , for b

• y - mx = b

• y + mx = b

• ^y/_mx = b

• y + mx = -b

Solve:
a - b - c = 9 , for a

• a = b + c + 9

• a = b - c + 9

• a = -b + c + 9

• a = -b - c + 9

Solve:
d = rt   , for t

• d/r = t

• r/d = t

• d + r = t

• d - r = t

Solve for w:
A = LW

• = ^L/_W

• = ^L/_A

• = A

• = ^A/_L
