PLS help. I'm having trouble and cant figure out these problems.
STatiana [176]

The Simplification of the following expression is;

  • x = 3
  • m = -30/7
  • v = -8.8
  • x = 3
  • u = -2.49
  • a = -3/70
  • p = -5
  • t = 9

<h3>Simplification</h3>

2.1x - 1 - 4.2x = 5.3

2.1x - 4.2x = 5.3 + 1

- 2.1x = 6.3

x = 6.3/-2.1

x = 3

7/8m - 4/7 - 5/6m = - 3/4

7/8m - 5/6m = -3/4 + 4/7

21m-20m/24 = -21+16/28

1/24m = -5/28

m = -5/28 ÷ 1/24

= -5/28 × 24/1

= -120/28

m = -30/7

4.3v + 10.75 - 4v = 8.11

0.3v = 8.11 - 10.75

0.3v = -2.64

v = -2.64/0.3

v = -8.8

9/7 + 9/7x - 6/7x =0

9/7x - 6/7x = - 9/7

(9-6)x /7 = 9/7

3/7x = 9/7

x = 9/7 ÷ 3/7

= 9/7 × 7/3

= 9/3

x = 3

6.9u - 2 - 3.2u - 10 = 2.8

3.7u = 2.8 - 12

3.7u = -9.2

u = -9.2/3.7

u = -2.49

8/5 = - 4a + 7/5 - 2/3a

8/5 - 7/5 = -4a - 2/3a

8-7/5 = -12a-2a/3

1/5 = -14/3a

a = 1/5 ÷ -14/3

= 1/5 × -3/14

a = -3/70

8p + 6 - 4p = -14

4p = -14 - 6

4p = -20

p = -20/4

p = -5

7 - (5t - 13) = -25

7 - 5t + 13 = -25

-5t + 20 = -25

-5t = -25 - 20

-5t = -45

t = -45/-5

t = 9
