5x + 5y = 19x = 3.8 - yory = 3.8 - x
Expression
I understand this expression to be 10x3 + 5x. Derivative: 30x2 + 5.
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)
27 + y = 42 - 4y so 5y = 15 making y = 3 and x = 6

5(x-y) is also equivalent to 5x-5y
0
It's an algebraic expression that can be simplified to: x-5y
No
-3
5(x + y)
5x(x - 2) + 5y(x - 2) = (5x + 5y)(x - 2) = 5(x - 2)(x + y)
The given expression can be simplified to: x-5y
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
5(y + 1)
