5x+3y=58 5x-3y=22 (3y gets cancelled bc 3y-3y=0, then add 5x with 5x, so you're left with) 10x=80, (divide both sides by 10) x=8 Now we look for y. So choose one formula from the two (let's say 5x + 3y=58) Substitute x for 8 so it will look like---- 5(8)+3y=58 Multiply 5*8--- so you get -- 40+3y=58 Subtract 40 from both sides and you're left with 3y=18 divide both sides by 3 you get y=6 In conclusion, x=8 and y=6 hence, (8,6)
