Solving Linear Equations: Variables on Both Sides

Question 1

Which statement is true about Micah’s solution?

Revolt · Accepted Answer

A: Micah’s solution is wrong. There are no values of x that make the statement true.

Question 2

Which linear equations have an infinite number of solutions? Check all that apply. (x – ) = (x – )8(x + 2) = 5x – 1412.3x – 18 = 3(–6 + 4.1x)(6x + 10) = 7(x – 2)4.2x – 3.5 = 2.1 (5x + 8)

Revolt · Accepted Answer

A: (x – ) = (x – ); C: 12.3x – 18 = 3(–6 + 4.1x)
