WebNow we want to solve for our y value. And we could substitute this back into either of these two equations. Let's use the top one. You could do it with the bottom one as well. So we know that 3 times x, 3 times 7 over 2-- I'm just substituting the x value we figured out into this top equation-- 3 times 7 over 2, plus 4y is equal to 2.5. WebUsing the Matrix Calculator we get this: (I left the 1/determinant outside the matrix to make the numbers simpler) Then multiply A-1 by B (we can use the Matrix Calculator again): And we are done! The solution is: x = 5. y = 3. z = −2. Just like on the Systems of Linear Equations page.

WebFeb 1, 2024 · x 4 = 2 x 1 + 2 x 3 = − 10 x 3 = − 9 + x 2. Finally subtract the last one multiplied by two from the second equation. x 4 = 2 x 1 = 8 − 2 x 2 x 3 = − 9 + x 2. Now it's clear that your system has an infinite number of solutions (one per each value given to x 2 ). This is not surprising since you have four variables and just three equations.
