Question

the difference of two number is 3 if the greater number is subtracted from 3 times of the smaller number the difference is 1 find the numbers​

Answer 1

Answer:

Let's begin with the first equation...

x+y=12

Let's substitute...

x+(3x-6)=12

4x-6=12

Let's add 6 to both sides as we proceed to isolate x...

6+4x-6=12+6

4x=18

Let's divide both sides by 4...

(4x)/4=18/4

x=9/2=4.5---smaller number

12-4.5=7.5---larger number

Let's check our work.

3x-6=y

3(4.5)-6=7.5

13.5-6=7.5

7.5=7.5
