Question

Solve the equation for y y+7x=9 (1 point) Y =

Then find the value of y for each value of x. (Type an integer or a fraction) (3 points)
When x=−2 , the value of y is
When x=0 , the value of y is
When x=4 , the value of y is

Answer 1

To solve the equation for y, we need to isolate y by subtracting 7x from both sides:

y + 7x = 9
y = 9 - 7x

Now, we can find the value of y for each value of x:
1. When x = -2
y = 9 - 7(-2)
y = 9 + 14
y = 23

2. When x = 0
y = 9 - 7(0)
y = 9
y = 9

3. When x = 4
y = 9 - 7(4)
y = 9 - 28
y = -19

Therefore, when x = -2, the value of y is 23.
When x = 0, the value of y is 9.
When x = 4, the value of y is -19.
