Solve each two-step. Show your work.

5v - 34= 26 3x + 7= 37






23 + 4x= 83 2.5c - 12= 13






12m - 17 + 139 121.1= -19.3 - 4d




-23z +234=970 7685=345 - 5d

Since these all are the same process and I'm sure you can figure it out, I'll solve only two of the problems:

5v - 34 = 26 (add 34 to both sides)
5v = 60 (divide by 5 on both sides)
v = 12

3x + 7 = 37 (subtract 7 from both sides)
3x = 30 (divide by 3 on both sides)
x = 10

In other words, isolate the variable on one side by doing the opposite operation: when there's addition, do subtraction; when there's multiplication, do division; and vice versa.

1. 5v = 60
v=12
3x = 30
x=10

2. 4x = 60
x=15
2.5c = 25
c = 10

3. typo?

4. -23z = 736
z = -32
-5d = 7340
d = -1468
