Solve the system of equations using the linear combination method. 7x+2y=29 3x-5y=30

For this case we have a system of two linear equations with two unknowns. whose variables are given by x and y respectively.

To solve the system by the linear combination method we follow the following steps:

1st step:

We multiply the first equation by 5:

2nd step:

We multiply the second equation by 2:

3rd step:

We add the equations:

Thus, we obtain the following:

4th step:

We substitute   in any of the equations:

Thus, the values of the variables areand .

The values are: and .

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

hope this .
