-10x-6y=0 -4x -6y=54 find the solution of this system of equations

Mathematics

You can see that the term -6y appears in both equations. In this cases, we can leverage this peculiarity and subtract the two equations to get rid of the repeated term. So, if we subtract the first equation from the second, we have

(-4x -6y) - (-10x-6y) = 54-0 \iff 6x = 54 \iff x = 9

Now that we know the value of x, we can substitute in any of the equation to deduce the value of y: if we use the first equation, for example, we have

-10x-6y=0 \iff -10\cdot 9 - 6y = 0 \iff -90-6y=0 \iff 6y = -90 \iff y = -15

Combine the like terms to create an equivalent expression. 5n-2n
Setler79 [48]

Answer:

3n

Step-by-step explanation:

When subtracting like terms (numbers, or variable expressions that have the same variable, like these), you add the coefficients (the numbers attached to the variable) to simplify the expression.

5n - 2n

 

   You have 5 "n"s and you subtract 2 "n"s, leaving you with 3 "n"s

Are the numbers (2,3)(1,5)(2,7) a function ?
Arturiano [62]

Firstly they are not numbers, they are ordered pairs or points with a form (x,f(x)) yes they probably lie on a function graph but that would be rather impossible to find out. The function may be linear, exponential, logarithmic etc. we can't tell. All we can tell is that if these ordered pairs P_{1,2,3} lie on a function graph P_{1,2,3}\in G_f where G_f=\{(x,f(x)):\forall x\in D_f\wedge f(x)\in T_f\} where D is definition set of function defined x's and T a transformation set of f(x)'s for this function. So yes they may lie on some lambda function but they themselves are nothing but an ordered pairs with no meaningful connection.

Hope this helps.
