Question

b) 3x + 4 = 5y -2
x -1 0 1 3 4
y​

Answer 1

Explicación paso a paso:

3x+4 = 5y-2

a) x = - 1

3x+4 = 5y-2

3(-1)+4 = 5y-2

-3+4 = 5y-2

1 = 5y-2

3 = 5y

y = 3/5

b) x = 0

3x+4 = 5y-2

3(0)+4 = 5y-2

0+4 = 5y-2

6 = 5y

y = 6/5

c) x = 1

3x+4 = 5y-2

3(1)+4 = 5y-2

3+4 = 5y-2

7 = 5y-2

9 = 5y

y = 9/5

d) x = 3

3x+4 = 5y-2

3(3)+4 = 5y-3

9+4 = 5y-2

13 = 5y-2

15 = 5y

y = 15/5

y = 3

e) x = 4

3x+4 = 5y-2

3(4)+4 = 5y-2

12+4 = 5y-2

16 = 5y-2

18 = 5y

y = 18/5
