Question

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?

Answer 1

Y=6 is correct!

Explanation:

Answer 2

The value of y is 6.

Explanation:

1) Since x = 1, you need to substitute x with 1.

2) Solve the equation

y = -4x + 10

y = -4(1) + 10

y = -4 + 10

y = 6
