(12 points) Explain how you will solve the pair of equations below by substitution

Show all the steps and write the solution in (x, y) form.

y = x + 4
y = −2x − 2

pls help
; - ;

(-4,6)

Step-by-step explanation

y = x + 4= −2x − 2

0=x+4

-4=x

y=-2(-4)-2

y=8-2

y=6

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
