$3x+2y=-8
1 x - y = -1

Step-by-step explanation:

in order to solve this system of equation we would say that let

3x+2y=-8 equation 1

1 x - y = -1 equation 2

from equation 2

1 x - y = -1 equation 2

x = -1 + y equation 3

substitute for equation 3 in equation 1

3x+2y=-8 equation 1

3( -1 + y) + 2y = 8

-3 + 3y +2y = 8

collect the like terms

-3 + 5y = 8

5y = 8 + 3

5y = 11

divide both sides by the coefficient of y

5y/5 = 11/5

y = 2.2

put the value y = 2.2 into equation 3

x = -1 + y equation 3

x = -1 + 2.2

x = 1.2

therefore th value of x is 1.2 and y is 2.2
