Solve the following system of equations using elimination by eliminating the y variable
first.
5x + 2y = 3
2x + 3y = 10

Respuesta :

The solution to the system of equations is x = -1 and y = 4

How to solve the system of equations?

The system of equations is given as:

5x + 2y = 3

2x + 3y = 10

Multiply the first equation by 2 and the second by 5.

10x + 4y = 6

10x + 15y= 50

Subtract the above equations

10x - 10x + 4y - 15y = 6 - 50

This gives

-11y = -44

Divide by -11

y = 4

Substitute y = 4 in 5x + 2y = 3

5x + 2 * 4 = 3

This gives

5x + 8 = 3

Subtract 8 from both sides

5x = -5

Divide by 5

x = -1

Hence, the solution to the system of equations is x = -1 and y = 4
