Begin by distributing 4 to -4x and 4, and it equals to 3x-16x+16=-75. then add -16x+3x=-13x, to have -13x+16=-75. subtract 16 on both sides (16-16 & -75-16) to have -13=-91. finally, divide -75 by -13 to have a final answer of x=7

3x+4(-4x+4)=-75

Order of operations requires distribution first:
3x+ -16x+16=-75

Then add common terms:
-13x+16=-75

Subtract 16 from both sides:
-13x = -91

Divide by -13 from both sides:
x = 7

Answer:

Step-by-step explanation:

make them less than or equal to signs, I don't know how to do that on a computer, I hope I am correct

point one on the left is -6, point 2 on the right is 0 (in terms of the x-axis, that's what domain is )

when there is arrows in the graph, the x/y is always in the middle.

Good luck! Hope I'm not late!
