X=12, because when you use the constant of proportionality, which in this case is three, that’s what you multiply by 4 in the numerator side to equal 12.
Do both as equation it will make it easier for her

1. 4y – y and 4 because “4y – y = 4.”
not equivalent because we don't know what y is
2.not equivalent
2x + 7x and 9x because “5 + 3 = 8.”
All you have to do is subtract them. 313-178=135
(0, 5) is a solution of the equation.
Step-by-step explanation:
- Step 1: To find an ordered pair, assume x or y to be 0 and solve for the other coordinate.
If x = 0, y = 0 + 5 = 5. Therefore, the ordered pair is (0, 5)
