X+ 3
A student solves the equation
2
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?
ОООО
O distributing x + 3 and then 3x + 5 to both sides of the equation
distributing X-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
