Simplify by combining like terms
-a2 + 2b2 + 1/4a2

• -a^2 + 2b^2
• -3/4a^2 + 2b^2
• -3a^2 + 2b^2 + 1/4
• -3/4a^2 + b^2

Simplify by combining like terms
y2/4 + y/3 + y2/3 - y/5

• 5y^2/12 + 3y/10
• 2y^2/9 + 4y/15
• 7y^2/12 + 2y/15
• y^2/6 + y/4 - y/2

• 3
• -2
• 1
• 5

Chap 1: Solve the equation
7(a+1) - 3a = 5 + 4(2a-1)

• 3/2
• 4/3
• 2
• 1

Chapter 1: c(x + 2) - 5 = b (x-3) solve for X

• x = (3b + 5 - 2c) / (c - b)
• x = (b + 5 - 2c) / (3 - c)
• x = (5 - 3b + 2c) / (b - c)
• x = (2c - 3b + 5) / (c + b)

Chap 1 : Solve the equation for X
a(3tx - 2b) = c(dx - 2)

• x = (c + 2b) / (3at + cd)
• x = (2c - 3ab) / (3t - d)
• x = (2b + c) / (3a - 2d)
• x = (2ab - 2c) / (3at - cd)
