1. 2x - 5 = x 2. -3b + 1 = 3b -5 3. (1/2)t + 7 = (3/2)t - 4 4. -2.3 + 1.2x = 5.9 - 2.9x 5. -7y -21 = -3y - 21

We need to solve each equation:

1. 2x - 5 = x

2x - x = 5

x = 5 ✅

2. -3b + 1 = 3b -5

5 + 1 = 3b + 3b

6 = 6b

b = 1 ✅

3. (1/2)t + 7 = (3/2)t - 4

t + 14 = 3t - 8

2t = 22

t = 11 ✅

4. -2.3 + 1.2x = 5.9 - 2.9x

2.9x + 1.2x = 5.9 + 2.3

4.1x = 8.2

x = 2 ✅

5. -7y -21 = -3y - 21

-21 + 21 = -3y + 7y

0 = 4y

y = 0 ✅

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
