Multiply 9 by 2
18 = 4
Then subtract 4 from both sides
18 - 4 = 0 will become

Since 14 ≠ 0, there are no solutions
Answer:
28x-35
Step-by-step explanation:
4x*7=28x
5*7=35
The answer would be (5, -2). This is because when you plug in the respective values in for x and y into the equation 3x - 3y = 21, you get 21, which is the desired answer.
3x - 3y = 21
3(5) - 3(-2) = 21
15 + 6 = 21
21 = 21
Hope this helped!
