6(2x-3)+4 = 16-(-18)
(6)(2x)+(6)(-3)+4 = 16+18
12+ -18+4 = 16+18
(12x)+(-18+4) = (16+18)
12x+ -14 = 34
12x-14 = 34
12x-14+14 = 34+14
12x = 48
12x/12 = 48/12
x = 4

Answer:

Step-by-step explanation:
Because the angles are adjacent to each other and form a straight line, they are supplementary angles. Supplementary angles add up to 180 degrees, therefore, you can add the two angle measures together and set them equal to 180.
(7x - 1) + (6x - 1) = 180 combine like terms
13x - 2 = 180 add 2 to both sides
13x = 182 divide by 13 on both sides

Exact form: 9/20 and decimal form: 0.45
