Unit 1 One-Variable Linear Equations/Inequalities Test Review

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a 

Solve:
C = 2πr, for r

• C/(2π) = r
• C + 2π = r
• C - 2π = r
• 2πC = r

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

Solve 2 + 5x + 2x = -12.

What is the solution to the equation 3(2x - 5) = x + 10?

• 9

• 6

• 8

• 5

Solve -2 = 4r + s for s.

• s = -2 + 4r
• s = 2 - 4r
• s = -2 - 4r
• s = 2 + 4r

3r - 5 = 2r

• No solution
• Infinitely many solutions
• r = 5

8v - 4(v + 8) = 8
