The first step is to include the - or + values for the given terms
To determine if the expressions (5x - 3xy - 5x) and (7xy - 4y) are equivalent, we can simplify the first expression. Simplifying (5x - 3xy - 5x) results in (-3xy). The second expression, (7xy - 4y), does not simplify to (-3xy). Therefore, the two expressions are not equivalent.
-2x-10y-12+3xy=4Put all x's to the other side and the ones with y's on the other:-10y+3xy=4+2x+12-10y+3xy=16+2xNow you factor a y from the side with the y's:y(-10+3x)=16+2xDivide both sides by (-10+3x):y=(16+2x)/(-10+3x)
The expression (4xy - 3xy + 2xy) consists of three terms: (4xy), (-3xy), and (2xy). Each term is a product of the coefficient (a number) and the variable part, which in this case is (xy). The coefficients are 4, -3, and 2, respectively. To combine the like terms, you would simplify the expression to ( (4 - 3 + 2)xy = 3xy).

3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
3xy - 3xy = 0
The first step is to include the - or + values for the given terms
18x3y5 + 9xy3 - 3xy = 3xy(6x2y4 + 3y2 - 1)

To determine if the expressions (5x - 3xy - 5x) and (7xy - 4y) are equivalent, we can simplify the first expression. Simplifying (5x - 3xy - 5x) results in (-3xy). The second expression, (7xy - 4y), does not simplify to (-3xy). Therefore, the two expressions are not equivalent.
2x + 5y = 2-3x - y = -3from the second equation:-y = -3 + 3xy = 3 - 3xsubstitute this value in the first equation:2x + 5(3-3x) = 22x + 15 - 15x = 2-13x + 15 = 2-13x = 2 - 15-13x = -13so, x = 1Now, solve for y :y = 3 - 3xy = 3 - 3 (1)y = zero
-2x-10y-12+3xy=4Put all x's to the other side and the ones with y's on the other:-10y+3xy=4+2x+12-10y+3xy=16+2xNow you factor a y from the side with the y's:y(-10+3x)=16+2xDivide both sides by (-10+3x):y=(16+2x)/(-10+3x)
3xy and 2xy. You can see that 3xy and 2xy have something in common with each other. They both have xy and the end of them. Hope this helped.

3xy + 3y2 = 3y (x + y)
