Question

Realizar los siguientes ejercicios
1) 5X + 7X = 24
2) -24 - 4 + 10 X= 2
3) 80 + X = 60
4) 18 - 8t + 12 t= 20
5) 4m + 7m-3m = 8
8) 48y + 20y-30 y - 12
7) 2-X= 10​

Answer 1

1) 5X + 7X = 24

12X = 24

X = 24/12

X = 2

2) -24 - 4 + 10 X= 2

-28 + 10X = 2

10X = 2 + 28

10X = 30

X = 30/10

X = 3

3) 80 + X = 60

X = 60 - 80

X = -20

4) 18 - 8t + 12 t= 20

-8t + 12t = 20 - 18

4t = 2

t = 2/4

t = 1/2 = 0,5

5) 4m + 7m-3m = 8

11m - 3m = 8

8m = 8

m = 8/8

m = 1

7) 2-X= 10

2 - 10 = X

-8 = X
