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