Answer:
(1.5, 16.5 )
Step-by-step explanation:
Given the 2 equations
3x - y = - 12 → (1)
x + y = 18 → (2)
Adding the 2 equations term by term will eliminate the y- term
4x + 0 = 6
4x = 6 ( divide both sides by 4 )
x = 1.5
Substitute x = 1.5 into (2) and evaluate for y
1.5 + y = 18 ( subtract 1.5 from both sides )
y = 16.5
solution is (1.5, 16.5 )
