Solve the equation for y. Then find the value of y for each value of x

Question

y + 7x = 11; x = -1, 0, 2

Answer 1

To solve the equation for y, we need to isolate y on one side of the equation. The equation is:

y + 7x = 11

To isolate y, we subtract 7x from both sides:

y = 11 - 7x

Now, we can substitute each value of x into the equation to find the corresponding value of y.

For x = -1:
y = 11 - 7(-1)
y = 11 + 7
y = 18

For x = 0:
y = 11 - 7(0)
y = 11
y = 11

For x = 2:
y = 11 - 7(2)
y = 11 - 14
y = -3

So the value of y for x = -1 is 18, for x = 0 is 11, and for x = 2 is -3.
