Get in function form.
- 3X - Y = 4
- 1(- Y = 3X + 4)
Y = - 3X - 4
----------------------------solve for X and Y by the 0 out method
- 3X - 4 = 0
- 3X = 4
X = - 4/3

yes 3xy=6
3xy - 3xy = 0
To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.
(x + 6y)(x - 3y)

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).
