Question

Y= -3/4x+3 and y=-12

Answer 1

x = 20, y = -12

Explanation:

y= -3/4x+3 and y=-12

x = 20, y = -12

Answer 2

x = 20, y = -12

Explanation:

`y=-(3)/(4)x+3\ and\ y=-12\\\\\text{Substitute the value of y to the first equation:}\\\\-12=-(3)/(4)x+3\qquad\text{multiply both sides by 4}\\\\-48=-3x+12\qquad\text{subtract 12 from both sides}\\\\-60=-3x\qquad\text{divide both sides  by (-3)}\\\\20=x\to x=20`
