Substitute x = -11 + y in 10x - 5y = -10 10(-11+y)-5y=10 distribute 10 with -11 and y 10(-11) + 10(y) - 5y=10 =>> -110 +10y -5y =10 combine like terms -110 +5y=10 add 110 to both sides to get the variable on one side 5y = 10+110 (120) 5y=120 divide both sides by 5 to get variable by itself 120/5=24 so y = 24 now replace the y with 24 to find x x=-11+24 24 - 11 = 13 x=13 therefore, y=24 and x=13 hope this helps :)
