Answer:
0 = 0
Step-by-step explanation:
Simplifying
7(x + -1y) = 7x + -7y
(x * 7 + -1y * 7) = 7x + -7y
(7x + -7y) = 7x + -7y
Add '-7x' to each side of the equation.
7x + -7x + -7y = 7x + -7x + -7y
Combine like terms: 7x + -7x = 0
0 + -7y = 7x + -7x + -7y
-7y = 7x + -7x + -7y
Combine like terms: 7x + -7x = 0
-7y = 0 + -7y
-7y = -7y
Add '7y' to each side of the equation.
-7y + 7y = -7y + 7y
Combine like terms: -7y + 7y = 0
0 = -7y + 7y
Combine like terms: -7y + 7y = 0
0 = 0
Solving
0 = 0
Answer:
Distributive Property
Step-by-step explanation:
When we're distributing something, there will always be a number or a variable is outside of a parenthisis signaling that you would need to multiply.
for Ex. 7(x-y), since there is a number that is connected to the outside of the parenthesis, that is a signal that we would need to multiply or distribute
