Answer:
8x+15=7 8x=-8 x =-1
Step-by-step explanation:
You want to simplify or factor it?
Simplify:
7 * χ + 7 * -3 +5χ
=7χ + -21 +5χ
=(7χ+5χ)+-21
=12χ-21
Factor:7(x-3)+5x
12x-21
=3(4x-7)
Answer:
I got 1 when I solved this problem
So all the angles on one side should equal 180.
50+55= 105
180-105=75
12x+3=75
12x=72
12*6=72
x=6
