Answer:
x = 1; y = 5
Step-by-step explanation:
-2x + 3y = 13
;
y = 7x - 2
Since the second equation is already solved for y, substitute y of the first equation with 7x - 2.
-2x + 3y = 13
-2x + 3(7x - 2) = 13
-2x + 21x - 6 = 13
19x - 6 = 13
19x = 19
x = 1
Now substitute x of the second equation with 1 and solve for y.
y = 7x - 2
y = 7(1) - 2
y = 7 - 2
y = 5
Solution: x = 1; y = 5
