♥ To solve this you are going to find x. ♥
♥ X in this case is representing a unknown variable, meaning we are not sure of the number x, and to finish the solution to your problem we have to find x.
♥ So to find x the first step is to simplify both sides of the equation.
♥ Starting with distribution:
♥ Now we want to flip the equation.
♥ Our next and almost final step, is to add the number -3 to both sides of our problem. This is going to help us tremendously.
♥ Now our last step before we get our answer is to divide both sides of the problem. In this case we are going to do this:
♥ And then because of that we get our final answer of: -4.

Answer: 13
Step-by-step explanation: 15 x 10 = 150
15x3= 45
150 + 45 = 195
Commutative Property, Breaking the problem 3x47 into simpler equation of 3x40+3x7
In seven years her mother will be 38 +7 = 45 years old.
She will be 5 times as old, so divide 45 by 5: 45/5 = 9. Elaine will be 9 years old then, so she is 9-7 = 2 years old now.
