Solve the linear equation by using substitution x-y=-4 3x-y=-10

(-3, 1)

Step-by-step explanation:

x-y=-4

3x-y=-10

y=x-(-4)=x+4

3x-(x+4)=-10

3x-x-4=-10

2x-4=-10

2x=-10+4

2x=-6

x=-6/2

x=-3

-3-y=-4

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

x=-3, y=1. (-3, 1).

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
