Algebra1 - Tramore maths circle
... x3 - 2x2 - 5x + 6 = 0 is a cubic equation. If we’re asked to solve this, we must try to values of x that make it true. We have no formula for this and doing it using brackets would be v. tricky! If we can find one root of the equation (one value of x that works) then we can reduce the problem to sol ...

Sect 8.2 Systems of Linear Equations in Three Variables
... A linear equation in three variables x, y, and z is an equation of the form Ax + By + Cz = D , where A, B, C, and D are real numbers with A, B, and C not all equal to zero. (For example, x + 2y + z = 6) A solution to a linear equation in three variables is an ordered triple of real numbers in the fo ...

... Taking just the last two equations, we have a system with two variables. We can solve it for x and y, then use the first equation to get z. So start by solving the second equation for x: x = 2y − 4. Now substitute this into the third equation to eliminate x, and solve for y: −3x + y = 2 −3(2y − 4) + ...
