1. -3( x - 4) = 2x + 4 - x
2. 4 + 2 (x - 2) = 2 (x - 1) + 2
3. 3(x - 4) = 2x - 7 + x
4. 4x + 15 = 3(x + 5)
5. 2(x - 3)
= x
4

6. 4x - 3
= 2x - 1.5
2

Step-by-step explanation:

1. -3( x - 4) = 2x + 4 - x

-3x + 4 = x + 4

4 = 2x + 4

2x = 0

x = 0

2. 4 + 2 (x - 2) = 2 (x - 1) + 2

4 + 2x - 4 = 2x + 2 + 2

2x = 2x + 4

x = 4

3. 3(x - 4) = 2x - 7 + x

3x - 12 = 3x - 7

x = 5

4. 4x + 15 = 3(x + 5)

4x + 15 = 3x + 15

x = 0

5. 2(x - 3)

for the rest i'm confuse what it is suppose to be

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
