Question

Solve the system of equations by elimination.
-X + y = -13
-8x - 4y = -8​

Answer 1

Answer:

X=5, y=-8

Step-by-step explanation:

-X + y =-13 equation 1

-8x-4y=-8 equation 2

4(-x+y)=4(-13). Multiply equation 1 by 4 to eliminate y

-4x + 4y =-52

———————————-

-4x + 4y =-52 equation 1 after multiplying by 4

-8x-4y=-8. Equation 2

-12x=-60 added 2 equations above

x=5

solve for y

-x+y=-13

-5+y=-13

y=-8

Answer 2

The value of x and y is 5 and -8.

Given that,

• The equations are -X + y = -13 and -8x - 4y = -8​.

Based on the above information, the calculation is as follows:

-X + y =-13 ........(1)

-8x-4y=-8 ........(2)

Now we have to multiply by 4 in equation 1  

4(-x+y)=4(-13)

-4x + 4y =-52

-8x-4y=-8

-12x=-60  

x = 5

Now the value of y is  

-x+y=-13

-5+y=-13

y = -8
