What is Systems of equations: Definition and 58 Discussions
In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought. An equation system is usually classified in the same manner as single equations, namely as a:
System of linear equations,
System of nonlinear equations,
System of bilinear equations,
System of polynomial equations,
System of differential equations, or a
System of difference equations

Ive been working on a bunch of non linear systems problems for homework and can't figure this one out:
y=xcubed
x-y=0
I get to the substitution stage and get x-xcubed=0, but you can't factor that so I am wondering what you do next to get the answers for x, and y.
Thanks in advance for...
Question: The weights of two beluga whales and three orca whales totals 36,000 pounds. The weights of one of the belugas and one of the orcas add up to 13,000 pounds. Using this information only, how much do the belugas weigh? How much do the orcas weigh?

Hello, I am stuck on the following problem.
How many milliliters of a 30% acid solution and a 55% acid solution must be mixed to obtain 100 milliliters of a 50% acid solution?
My solution:
Let X = The unknown milliliters of 30% acid.
Let Y = The unknown milliliters of 55% acid.
(1) X + Y =...
I need to solve this system of equations.
7/10S + 1D <=630
1/2S + 5/6D <= 600
1S + 2/3D <=708
1/10S + 1/4D <=135
I attempted to use the Excel solver to figure it out, but I couldn't understand completely how to work it.
Any ideas on how I can get started?
Hello everyone
I started out with 2 matrices, which are 2 separate problems but both want the same thing. It says Solve the system.
Here are the 2 problems:

Hello, could someone please help me out with the following questions?
Q. Determine the conditions on a, b, c so that the following systems are consistent and find any solutions.
a)
\begin{array}{l}
x + 2y - 3z = a \\
3x - y + 2z = b \\
x - 5y + 8z = c \\
\end{array}
b)...
