Step-by-step explanation:
To write an equivalent expression, we can combine like terms. So m +7m is 8 and we get 6(8m+2).
Here are a few others:
48m+12
6(m+m+m+m+m+m+m+m+2)
3(16m+4)
6m+12+42m
6m+6m+6m+6m+6m+6m+6m+6m+2
and the list goes on...
X + 19 + 7x + 9 = 180
8x + 28 = 180
8x = 180 - 28
8x = 152
X = 152 : 8
X = 19
X=80, y=140,z=20
