Solve this system of linear equation. separate the x- and y-values with comma. -6x=-4-y -7x=-22+y

(x,y)=(2,8)

Step-by-step explanation:

-6x = -4 -y

-7x = -22 +y

Rearranging the above equations

-6x +y +4 =0 => eq(1)

-7x -y +22 =0 => eq(2)

Adding eq(1) and eq(2)

-6x +y +4 =0

-7x -y +22 =0

-13 x +26 =0

-13x = - 26

x= -26/-13

x= 2

Putting value of x in eq (1)

-6(2) + y +4 =0

-12 +y+4 =0

y-8=0

y=8

So, values of x and y are 2 and 8

(x,y)=(2,8)

2,8

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
