x-5y=0. (times the top row by 3 and bottom 2x-3y=7. by 5 to get the y values the same) 3x-15y=0 10x-15y=35 as the signs before the y value are the same, subtract the other top values from the bottom. (all excluding the y values). so: 3-10=-7 and 0-35=-35 -7x=-35 -x=-5 x=5 substitute your x back into any of the two equations, here I'll use 2x-3y=7 2(5)-3y=7 10-3y=7 10-7=3y 3=3y y=1 hope this helped
