Answer:
Step-by-step explanation:
A) for this we want to solve for x
we first have to ditribute 2 to 9x-6 and 6 to 3x-2
18x - 12 = 18x -12 + 2 --> 18x - 12 = 18x - 10
add ten to both sides 18x -12 (+10) = 18x
18x - 2 = 18x since you can solve it theirs no solution
B) you combind like terms --> 4x + 8 = 4x + 8
since their the same on both sides that means they have infinante solutions

Answer:
150cm^2
Step-by-step explanation:
Answer:
x = 50°, y = 50°
Step-by-step explanation:
⇒ x + x + 80° = 180°
⇒ 2x = 180° - 80° = 100°
⇒ x = 100°/2 = 50° ∴ y = x = 50°
