I can't figure any of these problems out any help would be nice peace.
Show all steps used to solve the problem.
1.5n + 6 = 4
3.b/3+5=7
4.17x/4=10
5.If 3a  9 = 6, what is the value of 4a  1?
6.

#1.
5n + 6 = 4
subtract 6 from both sides
5n+66 = 46
5n = 10
divided both sides by 5
5n/5 = 10/5
n = 2
.

.
#4
17  x/4 = 10
multiply both sides by 4
68  x = 40
subtract 68 from both sides
6868  x= 4068
x = 108
divide both sides by 1
x = 108
do the rest the same way
