A student solves the equation *73 - 3x + 5
5 using the steps in the table.
Original
equation
x + 3
2
3x + 5
5
Cross multiplication
Distributive property
Subtraction property of equality
5(x + 3) = 2(3x + 5)
5x+15= 2(3x + 5)
5 = x
Which method of solving for the variable could be used instead of cross multiplication?
distributing x + 3 and then 3x + 5 to both sides of the equation
distributing - 3 and then 3x - 5 to both sides of the equation
using the multiplication property of equality to multiply both sides of the equation by 10
