Question

Part 1: Explain, in complete sentences, how you would use the elimination method to solve the following system of equations. (4 points)

Part 2: Provide the solution to the system. (2 points)

8x + 5y = 3
7x – 3y = 10

Answer 1

First multiply both equations by a number to either cancel out x or y.

Answer 2

In this case you would want to cancel out y, and then solve for x .

Answer 3

Part 1:
To eliminate x:
Multiply each term of the first equation by the coefficient of x in the second equation.
Multiply each term of the second equation by the coefficient of x in the first equation.
Subtract them to get rid of x and solve for y.
Then solve for x.

For part 2 use the method outlined in Part 1 to solve for x and y.

Answer 4

i need like specific stuff.. ive tried and got it wrong every time...

Answer 5

8x + 5y = 3
7x - 3y = 10

Multiply each term of first equation by 7:
56x + 35y = 21

Multiply each term of second equation by 8:
56x - 24y = 80

Subtract the above two equations:

(56x - 56x) + (35y - (-24y)) = (21 - 80)
59y = -59
So y = -1

Put y = -1 in 8x + 5y = 3 and solve for x

Answer 6

thank you! that helped out alot !
