Answer:
y = 5/3
x = 8/3
Steps:
y = x - 1
2x + y = 7
Substitute y = x-1
(2x + x - 1 = 7)
Simplify: 3x - 1 = 7
Isolate x: 3x - 1 = 7: x=8/3
Plug the valuse of x into the other equation (y = x- 1): y = 8/3 - 1
8/3 - 1 = 5/3
y = 5/3
y = 5/3, x = 8/3
I believe the answer is the first one because it contains a negative fraction and in the chart some of the numbers are negative
Answer:
C. Even

Any multiple of 2 is an even number.
27 is 3³, so the result cannot be a perfect square.
The product of two numbers, neither of which is 1, cannot be prime.
What if I wrote + 38 - 28 .
Would you be able to solve it that way ?
They're both the same number.
