Given: -5x+2/7 - -4
Prove : X=6
I NEED 4 STATMENTS AND 4 REASON WHY!!
Picture Below

1. Directly put 6 in place of x so it would be.

-5(6) + 2 = -4*7

-30 + 2 = -28

-28 = -28

2. Find the value of x.

-5x + 2 = -7*4

-5x = -28 - 2

-5x = -30

x = 6 (because 30 is divisible by 5 at 6)

3. Make Right hand side and Left hand side equal. To make it equal just put    6 in place of x.

(-5(6) + 2)/7 = -4

(-30 + 2)/7 = -4

-28/7 = -4

-4 = -4

RHS = LHS (hence proved x = 6)

Step-by-step explanation:

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
