Answer: x = 60</h3>
Work Shown:
a+x = 180
120+x = 180
x = 180-120
x = 60
Side note: angles 'a' and x are same side interior angles, which are supplementary whenever we have parallel lines like this.
1 → B
multiply each term in the parenthesis by the 6 outside
6(b-7) = 6b - 42
2 → D
multiply each term in the parenthesis by the 3 outside
3(4x+6y+2) = 12x+18y+6
3 → A
the value outside the parenthesis is -1, hence each term inside is multiplied by -1
-1(6x+5y) = -6x -5y
