Answer:
See below.
Step-by-step explanation:
All the equations are one-step equations.
In each case, see what operation is being done to the variable, and do the opposite operation to both sides.
1.
t + 1.32 = 3.48
1.32 is being added to t.
Subtract 1.32 from both sides.
t + 1.32 - 1.32 = 3.48 - 1.32
t = 2.16
2.
b - 4.22 = 7.08
4.22 is being subtracted from b.
Add 4.22 to both sides.
b - 4.22 + 4.22 = 7.08 + 4.22
b = 11.3
4.
h + 4/9 = 7/9
4/9 is being added to h.
Subtract 4/9 from both sides.
h + 4/9 - 4/9 = 7/9 - 4/9
h = 3/9
h = 1/3
5.
-5/8 = x - 1/4
1/4 is being subtracted from x.
Add 1/4 to both sides.
-5/8 + 1/4 = x - 1/4 + 1/4
-5/8 + 2/8 = x
-3/8 = x
x = -3/8
7.
3.2c = 9.6
c is being multiplied by 3.2.
Divide both sides by 3.2.
3.2c/3.2 = 9.6/3.2
c = 3
8.
-5.04 = 1.26d
c is being multiplied by 1.26.
Divide both sides by 1.26.
-5.04/1.26 = 1.26d/1.26
-4 = d
d = -4
10.
-2/3 = 3/4t
t is being multiplied by 3/4.
Divide both sides by 3/4 which is the same as multiplying both sides by 4/3.
-2/3 * 4/3 = 3/4t * 4/3
-8/9 = t
t = -8/9
11.
w/2.5 = 4.2
w is being divided by 2.5.
Multiply both sides by 2.5.
w/2.5 * 2.5 = 4.2 * 2.5
w = 10.5
