Answer 1

1. x - 12 = 14 {brother's age minus 12 equals sister's age}

x = 26 {added 12 to each side}

Your brother is 26.

2. x+8.95=21.35

now you must subtract 8.95 by both sides which equals x =12.4

3. 29 compact cars.

The total number of vehicle is 37. So you can just subtract 37 by 8 which gives 29.

4. x +73=95

subtract both sides by 73. which equals 22

5. $160 He originally spent $123.45 and was left with $36.55 you just add both numbers and that's what you get altogether.

6. X-225=548

Solve for x

Add 225 to both sides. So x - 753
