Answer:
3y - 5 + 2y = 7
Step-by-step explanation:
Subtracting 5 from the second equation gives ...
x = 3y -5
Using the expression on the right for x in the first equation gives ...
x + 2y = 7 . . . . . . . . first equation
(3y -5) +2y = 7 . . . . with expression substituted for x
3y - 5 + 2y = 7 . . . . with parentheses removed
<span>x − 3y = −2
x + 3y = 16
----------------add
2x = 14
x = 7
</span>x − 3y = −2
7 − 3y = −2
<span>-3y = -2 -7
-3y = -9
y = 3
so x = 7 and y = 3
answer is </span><span>A) (7, 3)</span>
