Which values of x and y satisfy 2x - y = 7 and 3x - 2y = 5 simultaneously?

X=4 and y=1 multiply 4 by 2 to give you 8 then minus y=1 will give you seven

To solve problems like this you can either graph or solve mathematically. To do the ladder we need to solve for one variable at a time. So lets cancel one variable out.

Multiply equation 1 by 2

This will give 4x-2y=14

Now we can get rid of y by subtracting 2 from 1

This will give x=9

Plug back in to either equation, i will use equation 2

3 (9) - 2y=5 simplify

-2y=-22 solve

Y=11
