99 asapsolve the system of equations using the linear combination method.5. 4x-9y=1 -4x+6y=-2 6. 3x-2y=142x+2y=6

The Linear Combination method is where you add both equations into a single equation.

First question:

Add the equations together:

Divide both sides by -3

Plug this value into the first equation and solve for x

Subtract both sides by 3

Divide both sides by 4

Second question:

Add both equations together:

Divide both dies by 5

Plug this value into the second equation and solve for y

Subtract both sides by 8

Divide both sides by 2

Let me know if you need any clarifications, thanks!

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
