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?
y =
Done
