Answer:
1) x = 30
2) x = 11.6
Step-by-step explanation:
1) 2x = 4x - 60 (vertical angles are equal)
subtract 4x from each side of the equation:
-2x = - 60
divide both sides by -2:
x = 30
2) 7x + 16 + 3x + 48 = 180° (supplementary angles add up to 180°)
combine like terms:
10x + 64 = 180
subtract 64 from both sides of the equation:
10x = 116
divide both sides by 10:
x = 11.6
Answer: Solution for 6-8x=-5x+6 equation:
6-8x=-5x+6
We move all terms to the left:
6-8x-(-5x+6)=0
We get rid of parentheses
-8x+5x-6+6=0
We add all the numbers together, and all the variables
-3x=0
x=0/-3
x=0
