Question

-10x + 3y = 5

x=y - 4

Answer 1

You can use the second equation to substitute the value of x in the first equation and solve for y.

x = y - 4

-10(y - 4) + 3y = 5

-10y + 40 + 3y = 5

-7y = 35

y = 5

Now that you have the value of y, you can use the second equation to find the value of x.

x = y - 4

x = 5 - 4

x = 1

So the solution of the system of equations is x = 1 and y = 5
