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.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
