What is the solution to the system of equations graphed below? y = x - 2 y = 4x - 5

ololo11 [35]

There are 3 available methods - Substitution , Elimination and Matrix.

The substitution method is used to eliminate one of the variables by replacement.

The elimination method is used for solving linear systems.

A Matrix is an array of numbers.

Lets use Substitution to solve this system.

$x-2=4x-5$

$-2=4x-5-x$

$-2=(4x-x)-5

 
$

$-2=3x-5$

$-2+5=3x$

$3=3x$

$3=3x / 3$

$x=1$

Now substitute $x=1$

$y=x-2$

$y=1-2

 
$

$y=-1

$

Hence - $x=1
 
y=-1$
