Ax+by=(a-b) , bx - ay =(a+b) simultaneous linear equations using cross multiplication

Step-by-step explanation:

Given:

To solve: the given linear equations

Solution:

Consider the equations:

By method of cross multiplication:

For equations:

Take

So,

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

only 10/60 isn't equivalent

hope this : )
