Question

Use the subtraction property of equality to complete the following statement:

If 10x + 6 = 21, then ___ = 15

Answer 1

10x

Explanation:

x=1.5 so for our equation to equal 15 you would have to multiply buy 10

Answer 2

10x + 6 = 21
first subtract 6 from both sides of the equation
10x=15
so I believe the answer you are looking for is 10x=15

If you take this one step further and solve for x then you divide both sides of the equation by 10 so then the solution is x=1.5
