Questions and Answers
Q 1 - Solve the following equation:

r + 4.8 = 12.5

Answer : B

Explanation

Step 1:

r + 4.8 = 12.5; Subtracting 4.8 from both sides

r + 4.8 − 4.8 = 12.5 − 4.8 = 7.7

Step 2:

So, r = 7.7 is the solution

Q 2 - Solve the following equation:

7.8 = −4.9 + p

Answer : C

Explanation

Step 1:

7.8 = −4.9 + p; Adding 4.9 to both sides

7.8 + 4.9 = −4.9 + p + 4.9 = 12.7

Step 2:

So, p = 12.7 is the solution

Q 3 - Solve the following equation:

14 = y + 5.6

Answer : A

Explanation

Step 1:

14 = y + 5.6; Subtracting 5.6 from both sides

14 − 5.6 = y + 5.6 − 5.6 = 8.4

Step 2:

So, y = 8.4 is the solution

Q 4 - Solve the following equation:

−q + 19.6 = 8.7

Answer : D

Explanation

Step 1:

−q + 19.6 = 8.7; Subtracting 19.6 from both sides

−q + 19.6 − 19.6 = 8.7 − 19.6 = −10.9

Step 2:

Changing signs on both sides

So, q = 10.9 is the solution

Q 5 - Solve the following equation:

−g + 3.3 = −15.5

Answer : A

Explanation

Step 1:

−g + 3.3 = −15.5; Subtracting 3.3 from both sides

−g + 3.3 − 3.3 = −15.5 − 3.3 = −18.8

Step 2:

Changing signs on both sides

So, g = 18.8 is the solution

Q 6 - Solve the following equation:

16.2 − u = 11.4

Answer : B

Explanation

Step 1:

16.2 − u = 11.4; Subtracting 16.2 from both sides

16.2 − u − 16.2 = 11.4 − 16.2 = −4.8

Step 2:

Changing signs on both sides

So, u = 4.8 is the solution

Q 7 - Solve the following equation:

3.8 + w = 8.7

Answer : C

Explanation

Step 1:

3.8 + w = 8.7; Subtracting 3.8 from both sides

3.8 + w − 3.8 = 8.7 − 3.8 = 4.9

Step 2:

So, w = 4.9 is the solution

Q 8 - Solve the following equation:

1.9 = q + 8.2

Answer : A

Explanation

Step 1:

1.9 = q + 8.2; Subtracting 8.2 from both sides

q + 8.2 − 8.2 = 1.9 − 8.2 = −6.3

Step 2:

So, q = −6.3 is the solution

Q 9 - Solve the following equation:

8.6 − z = 10.2

Answer : D

Explanation

Step 1:

8.6 − z = 10.2; Subtracting 8.6 from both sides

8.6 − z − 8.6 = 10.2 − 8.6 = 1.6

Step 2:

Changing signs on both sides

So, z = −1.6 is the solution

Q 10 - Solve the following equation:

11.7 = m + 13.5

Answer : B

Explanation

Step 1:

11.7 = m + 13.5; Subtracting 13.5 from both sides

11.7 − 13.5 = m + 13.5 − 13.5 = −1.8

Step 2:

So, m = −1.8 is the solution
