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
-X = -1
x=1
What is the value of y?
