So just find the factors of 90
90=2 times 3 times 3 times 5
so the factors could be
2,3,15
2,9,5
6,3,5
10,3,3
there are 4our
To get faster assistance type this question up on google for a answer immediately
2x=5y
x-y=111
x=111+y
so 2x=5y is
2(111+y)=5y
222+2y=5y
2y-5y=-222
-3y=-222 (divide by -3 both sides of the equation)
y=-222/(-3)= 74
x=111+y = 111 +74 = 185
so the first number is 185 and the second is 74
