Sometimes, you end up with an equation with no variables instead. Double check your work, and make sure you are plugging the (rearranged) equation one into equation two, not just back into equation one again. There are more equations than unknowns which often means there is no solution in the traditional sense. For the case at hand, each equation may be represented as a straight line lying in a plane.

We can try to solve it as if we had just 2 variables, x and y. Subtract the first equation from the second to get x = 3 z + 7. Then since y = 5 − x we get y = − 3 z − 2. Hi everyone this should be a pretty easy question. I have two equations with two unknowns. 1. -161.20 +2.7Ts -2.7Ta +3.91x10^-8 Ts^4 -5.67x10^-8 Ta^4 =0.

We want to eliminate x, what that means is, a very convenient way to do that, would multiply the second equation by -2. So every single part of that second equation. Gets multiplied by -2 and then we will add the two equations. The -2x the +2x will cancel we will get -y = -7 multiply by -1, we get y = 7 then we could plug in and solve for x. Equation 1: x − 2 y = 6 Equation 2: 3 x + y = 4. \begin{aligned} \text{Equation 1: }x-2y &= 6 \\ \text{Equation 2: }3x+y &= 4. \end{aligned} Equation 1: x − 2 y Equation 2: 3 x + y = 6 = 4.

Then since y = 5 − x we get y = − 3 z − 2. Thanks to all of you who support me on Patreon. You da real mvps! $1 per month helps!! :) !!
