60xy
Find the greatest common divisor 15xy55y? 15xy = (3)(5)(x)(y) & 55 y = (5)(11)(y). The common factors are 5 & y. Hence 5y = gcf of 15xy & 55y.
The LCM of these numbers is 25y. LCM is Least Common Multiple.
(2x + 3y)(2x + 5y)
2(x - 5y)
GCF(18xy, 15xy) = 3xy LCM(18xy, 15xy) = 90xy
10x2 - 20xz + 15xy = 5x (2x - 4z + 3y)
60xy
x = 1
2x+5y=20 Solve for y -2x -2x 5y=20-2x 5 5 5 y=4-2x 5
0 = -2x + 5y - 15 -5y = -2x - 15 y = 2x/5 + 3
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers (or expressions). You have only one expression in the question: 15xy. Also, if 5x3y is different from 15xy then multiplication is not commutative in whatever set these belong to. In that case it is impossible to find the LCM without information about the rules of "multiplication" in this set.
2X - 5Y = 2- 5Y = - 2X + 2Y = (2/5)X - 2/5==================
2X - 5Y = 10 ???? If so. 2X - 5Y = 10 - 5Y = - 2X + 10 Y = (2/5)X - 2 ================
Well, the way you wrote it, you would have:(4x - 5y - 3) x 3x + 5ywhich would give12x^2 - 15xy - 9x + 5yBut, if you meant the quantity (3x + 5y), then you would have:(4x - 5y - 3) x (3x + 5y)which would give12x^2 - 15xy - 9x + 20xy - 25y^2 - 15yand combining terms12x^2 - 25y^2 + 5xy - 9x - 15y
2x-5y = -10 -5y = -2x-10 y = 2/5x+2 which is in slope intercept form
The LCM is 30xy.
