Resuelve los siguientes sistemas de ecuaciones lineales utilizando el método de sustitución (verifica tu respuesta)

1) x + 2y = –1

2x + y = 4

2) 3x + y = –17

2x – 3y = 7

3) 3x + 2y = 14

x – 2y = 2

4) 2x – 3y = 8

9y – 6x = –2

5) 7x + 2y = –5

5y – 7x = 12

6) 2x – 3y = 13.8

5x + 2y = 6

7) 6x + 5y – 7 = 0

3 + 7y + 2x = 0

8) 5x + 4y = 4

3x – 2y = –8.6

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
