Question

Solve the equation for y. y+7x=10 (1 point)
Then find the value of y for each value of x. (Type an integer or as a simplified fraction) (3 points)
When x=−1 , the value of y is
When x=0 , the value of y is
When x=3 , the value of y is

Answer 1

y = 10 - 7x

When x = -1:
y = 10 - 7(-1)
y = 10 + 7
y = 17

When x = 0:
y = 10 - 7(0)
y = 10
y = 10

When x = 3:
y = 10 - 7(3)
y = 10 - 21
y = -11

Therefore, when x = -1, y = 17; when x = 0, y = 10; and when x = 3, y = -11.
