Solve the system of equations by graphing. {y=x-6 {y=3x-8 Show work please

1 answer:

7 0

You should subtract left sides and right sides in order to make y disappeared
and you will have the following:

y - y = (x - 6) - (3x - 8) => 0 = x - 6 - 3x - 8 => 0 = -2x - 14 =>

2x = -14 => x = -14/2 = -7

Now you can use -7 in the system and you will get y
y = -7 - 6 = -13

So your answers will be:
x=-7 and y=-13

Answer: 5x+3

Let's go over this problem step by step:

First, you need to combine all the line terms.

2x + 1 + 3x + 2

Next, you get this equation:

( 2x + 3x ) + ( 1 + 2 )

2x and 3x is 5x. 1 and 2 is 3.

So your final answer is 5x+3.
