y=x-9
solve for x

• x=9-y

• x=9y

• x=y+9

• x=9/y

2d-1=s
solve for d

• d=2s+1

• d=2s-1

• d=(s+1)/2

• d=(s-1)/2

Solve for a.

• a = pw

• a = p/w

• a = w/p

• a = w + p

S=6n-12
solve for n

• n=(S/6)+2

An algebraic expression that contains only one term is called

• Monomial

• Binomial

• Trinomial

• None of the above

If F = kx, rearrange to find x.

• x = F/k

• x = k/F

• x = F + k

• x = F - k

Rearrange the formula A = l × w to solve for w.

• w = A + l

• w = A × l

• w = A - l

• w = A / l

Rearrange the equation V = lwh to express l.

• l = V / (wh)

• l = V * (wh)

• l = V - (wh)

• l = V + (wh)

If P = 2(l + w), rearrange to find l.

• l = P/2 + w

• l = P/2 - 2w

• l = (P/2) - w

• l = P - 2w

Rearrange the formula d = rt to solve for t.

• t = dr

• t = r/d

• t = d + r

• t = d/r
