2x + 3 = 2x + 7 5x + 5 = 5x + 4

Question

2x + 3 = 2x + 7 5x + 5 = 5x + 4

Question 2: Infinite Solutions
Consider the two equations you circled, with infinite solutions. Solve the equations.

What does it mean to have infinite solutions?

Answer 1

Having infinite solutions means that any value of the variable will satisfy the given equations. In other words, the equations represent the same line or lines, and any point on the line(s) will be a solution to the equations.
