Question

Please help me this due today - two-step equations (20 pts)

1: m/8 + 15 = 20
2: 4 = m/3 -6
3: 44 = 4t + 8
4: 15+ 2x = 75

Answer 1

1:

`(m)/(8) + 15 = 20 \\ m + 120 = 160 \\ m = 160 - 120 \\ m = 40`

`4 = (m)/(3) - 6 \\ 12 = m - 18 \\ - m = - 18 - 12 \\ - m = - 30 \\ m = 30`

44=4t+8

-4t=8-44

-4t=-36

t=9

And the last one is

15+2x=75

2x=75-15

2x=60

x=30

Hope this helps :)
