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!

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
