Question

Comencemos con unas ecuaciones lineales ba
-3x
-2m
1. 4x – 7x = 8
2. 5m – 3m = 6
3. 3y - 25 = 12
4. 5x - 2x + 4 = 3x - 2
5. 5y - 7 = 3y + 8
6. 3n + 4 + 2n = 3n - 5
7. -3m - 6 + 2m = -8 + 4m
8. 2p - 5 + 7p = 5p - 3.p + 6
9. 2s - 3s + 4 = 5s-2-85
10. 3r - 10r - 2r = 2 + 8r - 3​

Answer 1

Respuesta:

1. 4x – 7x = 8

-3x = 8

x = 8 / -3

2. 5m – 3m = 6

2m = 6

m = 6/2

m = 3

3. 3y - 25 = 12

3y = 12 + 25

3y = 37

y = 37 / 3

4. 5x - 2x + 4 = 3x - 2

5x - 2x - 3x = - 4 - 2

0 = - 6

5. 5y - 7 = 3y + 8

5y - 3y = 8 + 7

2y = 15

y = 15 / 2

6. 3n + 4 + 2n = 3n - 5

3n + 2n - 3n = - 4 - 5

2n = -9

n = -9 / 2

7. -3m - 6 + 2m = -8 + 4m

-3m + 2m + 4m = - 8 + 6

3m = - 2

m = -2 / 3

8. 2p - 5 + 7p = 5p - 3p + 6

2p + 7p - 5p + 3p = 5 + 6

7p = 11

p = 11 / 7

9. 2s - 3s + 4 = 5s-2-85

2s - 3s - 5s = -4 - 2 - 85

-6s = -91

s = - 91 / - 6

10. 3r - 10r - 2r = 2 + 8r - 3

3r - 10r - 2r + 8r = 2 - 3

-1r = - 1

r = -1 / -1

r = 1

Espero haberte ayudado (:
