Answer:
By multiplying both side with the inverse of the coefficient of x
Step-by-step explanation:
coefficient of x = -6/4
inverse of coeefficient =-4/6.
multiply both sides.
x = 12(-4/6) = -8
B and D
Table attached
m<1 = 175 degrees
3x + 10 = 2x + 15
-2x - 10 = -2x - 10
x = 5
180 - 5 = 175 degrees
12 + 6m
