Solve 3x-y=-12
x+y=18

(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 )

the correct answer is a.) bc< mn 5 stars if this you : )
