Answer:

x = -3

Step-by-step explanation:

The equation of any linear function is y = mx + c, where m is the gradient and c is the y-intercept

The equation of the function is y = -x + 4

The gradient is negative one (hence 1x) and the y-intercept is 4

We need to find what x equals when the y = 7

7 = -x + 4

Rearrange

7 - 4 = -x

-x = 3

x = -3
