One Variable Equations and Literal

Solve for x:
7 - 2(10x + 1) = 25

• 2/5

• 2

• 1

• -1

Solve for x:
3(5x + 10) + 10 = 6x - (x + 10)

To solve an equation, the goal is to __________ the variable on one side.

• Evaluate

• Leviate

• Isolate

• Reciprocate

A letter or symbol that represents an unknown value is called ______________.

• Variable

• Radicand

• Coefficient

• Constant

d = rt, solve for r

• r = dt

• r = d/t

• r = d - t

• r = d + t

Solve for T, B = T - Lc

• T = BLc

• T = B - Lc

• T = B + Lc

S = 3F - 24  Solve for F

• F = (S + 24)/3

• F = S/3 + 24

• F = 3S + 24

• F = 3(S + 24)

Solve for s:
2s = 6t + 8w

• s = 12t + 16w

• s = 6t + 4w

• s = 3t - 4w

• s = 3t + 4w

Solve for x:
5 + 3x = 8x - 15

• 10

• 4

• 2

• 20/11

What are inverse operations?

• Absolute values

• Opposite operations used in isolating a variable

• Operations used for only inequalities

• Unknown quantity represented by a letter or symbol
