Answer:
Many of these are just the same equation in different orders.
42 + 6 = 48
6 + 42 = 48
48 = 6 + 42
48 = 42 + 6
42 = 48 - 6
48 - 6 = 42
6 = 48 - 42
48 - 42 = 6
7 + 5v - 0 + 2v - 1
5v + 2v + 7 - 1 - 0
7v + 6 (Answer)
Answer:
x = 4
31x + 6 = 130
12x + 2 = 50
Step-by-step explanation:
two angles side by side are equal to 180.
(31x + 6) + (12x + 2) = 180
43x + 8 = 180
43x = 172
x = 4
31x + 6 = 124 + 4 = 130
12x + 2 = 48 + 2 = 50
A solution to a equation is when the variable is substituted fully. That makes the equation true.
