Question

2. Solve the system using substitution y = 4x – 5 y = 2x - 6

Answer 1

(-0.5,-7)

Explanation:

`y=4x-5\\y=2x-6`

We can see in these 2 equations they equal the same thing which is y so we can set the 2 equations equal to each other like this

`4x-5=2x-6`

Subtract 2x from both sides

`2x-5= -6`

Add 5 to both sides

`2x= -1`

Divide both sides by 2

`x= -0.5`

Now we can replace x with -0.5 in one of the equations and will put it in the first equation to find y

`y=4(-0.5)-5\\y= -2-5\\y= -7`

So the system of equation solution is (-0.5,-7)
