theres 2 different methods u could do. u could solve for either x or y in one of the equations and replace the one you solved for. thatd be the easiest with those numbers
x = 23 - y
7x + 5y = 175
Substitute 23 - y for x in the second equation and solve for y. Put that value in the first equation to find x. Check by putting both values into the second equation.
