You can put this solution on YOUR website! Hi,x+5y-4z=-102x-y+5z=-9 ||eliminating z13x + 21 y = -862x-y+5z=-92x-10y-5z=0 ||eliminating z4x – 11y = -9 13x + 21 y = -8621x = -105, x = -5 and y = -1 and z = 0
Solve the system by elimination.. x+5y-4z=-10…. – Brainly.com – You have three equations and assuming that the x, y, and z all have the same value for all equations. The best way to solve this is to start by rearranging the first equation to isolate X. X+5y-4z=-10.Siyavula's open Mathematics Grade 10 textbook, chapter 4 on Equations and inequalities covering Solving simultaneous equations. We can solve simultaneous equations algebraically using substitution and elimination methods. We will also show that a system of simultaneous equations… – 2 4x + 3y = -1 -4x +10y = -38 13y = -39 y = -3 We substitute this to the first equation: 4x – 9 = -1 4x = 8 x = 2.

Solve the system by elimination: 4x + 3y = -1 2x – 5y = 19 – Brainly.ph – 1 ) 1st and 2nd equation (multiply 1st by -2 ): -2x – 10 y + 8 z = 20 2 x – y + 5 z = -9 – – 11 y + 13 z = 11 / * ( -20 ) 1st and.Use Gaussian elimination to solve the following system of equations. First, the system is written in "augmented" matrix form. Then, legal row operations are used to transform the matrix into a specific form that leads the student to answers for the variables.Elimination (or multiplication/addition or linear combinations) is a method that adds/subtracts multiples of one equation to multiples of the other equation. Multiply the top equation by 2 and the bottom equation by 3: 8x+6y=-10 9x-6y=-27 Note that the coefficient of y is the same, but opposite in sign.
