7x - 3y = 42x - 4y = 1the solution to the system of equations is

7x - 3y = 4
2x - 4y = 1

Multiply the first equation by 4.
Multiply the second equation by -3

28x - 12y = 16
-6x + 12y = -3

Now add the equations.

22x = 13

x = 13/22

Now substitute x = 13/22 in the first original equation and solve for y.

7 * 13/22 - 3y = 4

91/22 - 3y = 88/22

-3y = -3/22

y = 1/22

x = 13/22, y = 1/22

y = 3/22

sorey ik so sorey i need and need to answer a few
