What is the x-value in the solution to this system of linear equations
2x - y = 11
X + 3y = -5
-3
o
0 2

x = 4

Step-by-step explanation:

2x - y = 11

X + 3y = -5

Multiply the first equation by 3

3(2x - y )= 11*3

6x - 3y = 33

Add this to the second equation to eliminate y

6x - 3y = 33

X + 3y = -5

7x = 28

Divide by 7

7x/7 = 28/7

x = 4

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
