What is the sum of the coefficients in the expression: 2x + 3y - 5?

• 0 (2 + 3 - 5 = 0)

• 1 (2 + 3 - 4 = 1)

• 5 (2 + 3 - 0 = 5)

• -1 (2 + 3 - 6 = -1)

What is the distributive property?

• a(b + c) = ab + ac

• a(b + c) = a + b + c

• ab + ac = a(b + c)

• a(b + c) = ab - ac

Simplify by combining like terms: 5a + 2b - 3a + 4

• 2a + 2b + 4

• 3a + 2b + 4

• 2a + 3b + 4

• 5a + 2b - 3

What is the first step in solving an equation?

• Isolate the variable on one side of the equation.

• Combine like terms on both sides of the equation.

• Multiply both sides by the same number.

• Check the solution by substituting back into the equation.
