Question

Resolver para cada variable
2b+10=20
2y+8=22
2v+7=9
3b-5=7
2u-5=1
2a+5=17
​

Answer 1

2b+10=20

2b = 20 - 10

2b = 10

b = 10/2

b = 5

2y+8=22

2y = 22 - 8

2y = 14

y = 14/2

y = 7

2v+7=9

2v = 9 - 7

2v = 2

v = 2/2

v = 1

3b-5=7

3b = 7 + 5

3b = 12

b = 12/3

b = 4

2u-5=1

2u = 1 + 5

2u = 6

u = 6/2

u = 3

2a+5=17

2a = 17 - 5

2a = 12

a = 12/2

a = 6
