Question

Solve this system of linear equations. Separate the x and the y values with a comma.

16x=50-14y
-7x=77-14y

Answer 1

3,7

Explanation:

Answer 2

16x = 50 - 14y
-7x = 77 - 14y

Rewrite the first equation.
Multiply the second equation by -1 and write under the first equation.
Then add the equations.

16x = 50 - 14y
7x = -77 + 14y

Add to get:

23x = -27

x = -27/23

Now substitute this value of x in the first original equation and solve for y.

16x = 50 - 14y


16(-27/23) = 50 - 14y

-432/23 = 1150/23 - 14y

-1582/23 = -14y

y = 113/23

-27/23, 113/23
