Answer:
x = -3, y = 5
Step-by-step explanation:
first, take the 3x + 17 = y and put it in place for the y in the second equation.
-3x=4x+17+4
then, solve the equation.
-3x=4x+21
-3x-4x=4x-4x+21
-7x=21
-7/-7x=21/-7
x = -3
substitute in other equation
4(-3) + 17 = y
-12 + 17 = y
y = 5
answers are x = -3 and y = 5
Answer: x=-3 and y=5
Step-by-step explanation: 4x+17=y, -3x=y+4
4x+17-17=y-17
4x/4=y/4-17/4
x= y-17/4
-3(y-17/4)=y+4
-3(y-17)/4=y+4+4(4)
-3(y-17)=4y+16
-3(y-17)
-3-(-3)(17)
-3y+3(17)
-3y+51-51=4y+16-51
-3y-4y=4y-35-4y
-7y/-7=-35/-7
y=5
x=5-17/4
-12/4
x=-3
x=-3, y=5
