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

Respuesta :

The value of y would be found by adding the variable value into the equation that you started with.
So y= -4(1)+10
-4+10= 6
Y=6
