Solve the linear system of equations using the linear combination method.<br> 4x-9y=20<br> 2x-6y=16
maxonik [38]

The solution is (-4,4)

Step-by-step explanation:

Given equations are:

4x-9y = 20\ \ \ \ Eqn1\\2x-6x = 16\ \ \ \ Eqn2

In linear combination method, we have to make coefficients of any one variable opposites by multiplying with an integer

So multiplying 2nd equation by -2

-2(2x-6y=16)\\-4x+6y=-32\ \ \ \ Eqn3

Adding Equation 1 and Equation 3:

4x-9y-4x+12y = 20-32\\3y = -12

Dividing both sides by 3

\frac{3y}{3} = \frac{-12}{3}\\y = -4

Putting y=-4 in equation 1

4x-9(-4) = 20\\4x +36= 20\\4x = 20-36\\4x = -16

Dividing both sides by 4

\frac{4x}{4} = \frac{-16}{4}\\x = -4

Hence,

The solution is (-4,4)
