Question

Resuelva las siguientes ecuaciones
1:2y=5
2:3+x=4
3:x-2=8
4:x-3 =9
5:3x=10
6:4y=20
7:x-4:21
8:-4x=8
9:y-4=10
10:y+3=5

Answer 1

1:2y=5
y = 5/2

2:3+x=4
x = 4 - 3 = 1

3:x-2=8
x = 8 + 2 = 10

4:x-3 =9
x = 9 + 3 = 12

5:3x=10
x = 10/3

6:4y=20
y = 20/4 = 5

7:x-4=21
x  = 21 + 4 = 25

8:-4x=8
x = -8/4 = -2

9:y-4=10
y = 10 + 4 = 14

10:y+3=5
y = 5 - 3 = 2

Answer 2

1: y=2,5
2 :x=1
3 :x=10
4: x=12
5: x=3,3
6: y=5
7:x=25
8:x=12
9:y=14
10:y=2
