Indeed, we can check \(ad-bc\) for the equations is very close to zero, which explains how sensitive the solution is to small changes of the parameters: we have \ for the first pair, and \ for the second pair. The x-intercept is found by finding the value of x when y 0, (x, 0). Our math solver supports basic math, pre-algebra, algebra, trigonometry. Now you are to solve it and find y, but u dont have enough information about the other variable i.e.

Method 1įor the first pair, subtract the second equation from the first to obtain \ Dividing through by \(0.00001\) then gives \ We can now add this to the second initial equation to eliminate \(y\) we get \ Now dividing through by \(1.99999\) gives \ and so also \įor the second pair, we can again subtract the second equation from the first, which this time gives \ Dividing through then gives \ Subtracting the second initial equation from this (to eliminate \(y\)) gives \ and so \ which in turn leads to \ Method 2įor the first system, multiply the second equation by \(0.99999\) and subtract it from the first one. Solve your math problems using our free math solver with step-by-step solutions. Lets say you have an equation in x and y.
Multiply equation a) by 2 and equation b) by 3 to form the. Here are two possible approaches to solving the equations. Step One: We need to find a way to equate either the x terms of the y terms in each equation. Solve the two pairs of simultaneous equations
