Question

Assigen
substitution.
The value of x in this system of equations is 1
38 + 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?
Done

Answer 1

The value of y is 6

Step-by-step explanation:

We are given the system of equations:

$3x+y=9\\y=-4x+10$

They have found the value of x by substituting the value of y in eq(2) in eq(1)

$3x + (-4x + 10) = 9\\-x + 10 = 9\\-x= -1\\x=1$

The value of x=1

We need to find value of y.

If we put value of x=1 into equation (1)

$3x+y=9\\3(1)+y=9\\y=9-3\\y=6$

So, The value of y is 6
