Question

Y= 5x + 13
and
y= x + 45

Answer 1

x=8 and y=53

Explanation:

Given function:

• y=5x+13
• y=x+45

Find x:

• the two equation, the x and are breaked apart..
• so find a number that they can both equal to together and has the same y.
• multiply by 8..
• 
  `5`·
  `8=40`

• combine the terms for x and 13
• 
  `40+13=53`

• since x is 8 then if we add 8 with 45 it should be 53...
• 
  `8+45=53`

y is:

• this means that y=53.

Therefore, x=8 and y=53..
