The value of x in this system of equations is 1
3x + y = 9
y=-4x + 10
1. Substitute the value of y in the first equation
2. Combine like terms
3. Apply the subtraction property of equality
4. Apply the division property of equality
3x + (-4x + 10) = 9
--x + 10 = 9
-I= -1
X=1
What is the value of y?
Y =
