Literal Equations

Identify each equation that is a

literal equation.

• 4a² + 3b - 7 = 12

• x² + 4x - 5 = 3x

• t = 3r - 5

• 2n + 2(n - 5) = 13 + n

• 3x + 15 = 3x - 12

Solve for x.

z = xy

• x = ^z/_y

• x = ^y/_z

• x = yz

• x = z - y

Solve for w.

lw = A

• w = l - A

• w = ^l/_A

• w = A - l

• w = ^A/_l

Solve for t.

x = r + t

• t = x - r

• t = x + r

• t = xr

• t = ^x/_r

Which is the BEST first step to solve the equation below for x?

y = mx + b

• Subtract m

• Subtract b

• Divide by x

• Divide by b

Solve -2 = 4r + s

for s.

• s = -2 + 4r

• s = 2 - 4r

• s = -2 - 4r

• s = 2 + 4r

Solve for b:

y = mx + b

• b = y - mx

• b = y + mx

• b = my + x

• b = my - x

Solve for F:

S = 3F - 24

• F = (S + 24)/3

• F = S/3 + 24

• F = 3S + 24

• F = 3(S + 24)
