Answer:
(x, y ) = (5, 4 )
Step-by-step explanation:
given the 2 equations
3x - 2y = 7 → (1)
- 3x + 5y = 5 → (2)
adding the 2 equations term by term will eliminate x
(3x - 3x) + (- 2y + 5y ) = (7 + 5 )
0 + 3y = 12
3y = 12 ( divide both sides by 3 )
y = 4
substitute y = 4 in either of the 2 equations and solve for x
(1 ) : 3x - 8 = 7 ( add 8 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
solution is (5 , 4 )
