|7 - x| >= 1
When solving for x inside an absolute value, you can set up two equations. One for the positive and one for the negative(since we’re dealing with absolutes.
We end up with:
7 - x >= 1
7 - x <= -1 (inequalities’ signs flip when multiplying or dividing by a negative.)
7 - x >= 1
7 - 1 >= x
X <= 6
7 - x <= -1
7 + 1 <= x
X>= 8
X: (-infinity, 6]U[8, infinity)

Answer:
x = 65/16, y = 37/16
Step-by-step explanation:
solve the system algebraically
x+3y=11
4x-4y=7
Try substitution.
let x = 11 - 3y
Plug in.
4(11 - 3y) - 4y = 7
44 - 12y - 4y = 7
44 - 16y = 7
37 = 16y
y = 37/16
x = 11 - 3*y
x = 11 - 3*(37/16)
x = 11 - 111/16
x = 65/16
