Answer:
(3, 2 )
Explanation:
given the simultaneous equations
7x - 3y = 15 → (1)
2x + 3y = 12 → (2)
adding the 2 equations term by term will eliminate y
(7x + 2x) + (- 3y + 3y) = 15 + 12
9x + 0y = 27
9x = 27 ( divide both sides by 9 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (2)
2(3) + 3y = 12
6 + 3y = 12 ( subtract 6 from both sides )
3y = 6 ( divide both sides by 3 )
y = 2
the solution is (3, 2 )
