6.
- X = 7x - 56
7.
5(n - 7) = 2r + 14
8.
6w - 33 = 3(4w - 5)

Answer 1

Explanation:

1. 5x-4 =4x

5x-4x =4

x=4

2. 7x=8x+12

7x-8x =12

-x=12

x= -12

3. 27-3x=3x+27

27-27 = 3+3x

0=6x

0/6 =x

x=0/6

4. 34-2x=7x

34 =7x+2x

34 =9x

34/9=9x/9

3.78=x

x=3.78

5. 5r-7 =2r+14

5r-2r=14+7

3r=21

3r/3 =21/3

r=7

6.-x=7x-56

56=7x+x

56 =8x

x=7

7. 5n -35 =2r +14

5n-2n =14+35

3n =49

n=16.33

8.6w-33 = 12w-15

-33+15= 12w-6w

-18=6w

-3=w
