Question

I did this one incorrectly I need to do substitution and show my work

Answer 1

Explanation:

Substitute y = -2x+3 into the value of y in the second equation:

`x + - 2x + 3 = 6`

Subtract:

`- x + 3 = 6`

Subtract 3 from both sides:

`- x = 3`

Find the inverse, or divide by (-):

`x = - 3`

Substitute -3 into the first equation:

`y = - 2( - 3) + 3`

Multiply:

`y = 6 + 3`

Add:

`y = 9`

Answer 2

• The value of x = –3
• The value of y = 9
