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
