Answer:
x = -2
y = 9
Step-by-step explanation:
to evaluate this system of equation we would say that
let
Y=-3x+3................................................. equation 1
Y=5x+19................................................... equation2
substitute equation 2 into equation 1
5x + 19 = -3x + 3
collect the like terms together
5x + 3x = 3 -19
8x = -16
divide both sides by the coefficient of x which is 8
8x/8 = -16/8
x = -2
put x = -8 into equation 1
Y=-3x+3................................................. equation 1
y = -3(-2) + 3
y = 6 + 3
y = 9
therefore the value of x and y is -2 and 9 respectively.
