Y=-3x+3
Y=5x+19
Solve this system by substitution

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.
