I think You should break it down to the First and third One because of
Answer:
81
Step-by-step explanation:
x = 6
Step-by-step explanation:
2 - 12 × x = -70
= -12x +2 = -70
Since they are vertical angles, they equal each other. Therefor the equation would be: 30x-29 = 20x+21
10x = 50
X = 5
After, you plug whatever x is back into the other equations.
20(5)+21 = 121 and 30(5)-29 = 121
