Oh, dude, using matrices for these two equations, you'd set up a system like this: [-4 4 -8] [x] = [0] and [1 -4 -7] [y] = [0]. Solve it however you want, like with Gaussian elimination or something, and you'll find the values of x and y that make both equations true. So, like, have fun crunching those numbers, I guess.

What does 4x times 4x equal?
4x × 4x = (4x)² = 16x²
How do you work out the equation 4x-10 equals -4x plus 22?
4x - 10 = -4x + 22 +4x+10=+4x +10 8x = 32 x = 4
Factor 16x2 - 25?
16x2 - 25 = (4x + 5) ( 4x - 5)
How do you solve 4x - 9 equals 35?
4x - 9 = 35 4x = 35 + 9 4x = 44 4x/4 = 44/4 x=11
What are some examples of word problems using integers?

4x-7y equals 13 -2x plus 7y equals -3?
One way to solve this system of equations is by using matrices. Form an augmented matrix in which the first 2x2 matrix is the coefficient matrix and the 2x1 matrix on its right is the answer. Now apply Gaussian Elimination and back-substitution. Using this method gives x=5 and y=1.
What is the answer using distributive property -3 plus v plus 4x-2?
v + 4x - 5
Factor using GCF 8x 10?

How do I get -1 using only 4's?
4x-4=-1
How do you solve a linear problem using a matrix?
To solve using matrices, you're usually given a set of 2 or more linear equations. Once you have that, isolate the variables and write numerically in the form of a matrix, dividing the right side from the left. Ex. : 2x + 3y = 7; 4x - y = 2 Isolating variables: [2 3 | 7] [4 -1 | 2] From there onwards, it should be easy to solve.
What are the chords for the song together by Tierra?
Intro Dmaj7-4X Em7-4x Em7-2x B6-2x Dmaj7-3x A13-1x Dmaj7-4x Em7-4x Em7-2x B6-2x Dmaj7-4x B7-4x Em7-4x F#m7-4x Em7-4x A13-4x Dmaj7-4x Em7-4x F#m7-8x Bm7-3x A13-1x Dmaj7-4x Em7-2x Dmaj7-2x Then they take the whole song one step up in to D#maj7 repeat the song using the same count like the start but you be in D#maj7 -4x _ _ _ Thank-you
4(x plus y) using distributive property?
It is 4x + 4y.
What equation using 4 fours equals 13?
4x + 2 = 54
Can you explain how to do 6x - 3y 30 and 4x 2 - y then find x y?
6x-3y=30 4x=2-y There are many ways to find the values of x and y. elimination substitution matrices on and on... Here's one. Set them both equal to y y=2x-10 y=2-4x So the right sides are both equal to y, therefore, they are equal to each other. 2x-10 = 2-4x 6x=12 x=2 plug 2 in for x on one of the equations y=2-4x y=2-4(2) y=-6
What is y equals 4x-10 and y equals 5-x solve using substitution?
By definition: 4x-10 = 5-x 4x+x = 5+10 5x = 15 x = 3 and y = 2
How do you solve the square root of 4x to the sixth power?
4x to the sixth can be expanded to (4x * 4x * 4x)(4x * 4x * 4x) or (4x to the third)(4x to the third) the square root of the above would be 4x to the third
