4x-3y=7 x=13-3y Solve for the variables.

x = 4

y = 3

Step-by-step explanation:

4x-3y=7

x=13-3y

Put x as 13-3y in the first equation.

4(13-3y) - 3y= 7

52 -12y - 3y = 7

-15y = 7 - 52

-15y = -45

y = 3

Put y as 3 in the second equation.

x = 13-3(3)

x = 13-9

x = 4

x = 4, y = 3

Step-by-step explanation:

4x-3y = 7

Putting x = 13-3y in the above equation

=> 4(13-3y)-3y = 7

=> 52-12y-3y = 7

=> 52-7 = 15y

=> 45 = 15y

=> y = 3

Now, x

=> x = 13-3y

=> x = 13-3(3)

=> x = 13-9

=> x = 4
