Answer:

Below.

Step-by-step explanation:

1. a^2 - b^2 = (a - b)(a + b)

a^2 and b^2 are 2 perfect squares and a^2 - b^2 are their difference.

2. The order of multiplication does not matter because in algebra multiplication is commutative ( meaning any order gives the same result).

How to solve 5x-4y=7 2y+6x=22 as a system of equations

ira [324]

Step-by-step explanation:

you subtract -4 by 7.

then you hav 5x=7

you divide 5x by 5 and seven by five so your x= that answer

then you put that number into the x in the second equtaion

then you subtract that number after multiplying the 6 by the number x equals

then you divide 2y by 2 and 22 by 2 and thats your y value
