Can someone please help me solve this equation (with working out)

x=12

Step-by-step explanation:

Let us make all the denominators equal. Since the greatest common factor  (gcf) is 6, let us make the denominator 6.

x/6 = x/6

2(2x/3) = 4x/6

6(10/1) = 60/6

Now let us solve the equation

x/6  +  4x/6   =  60/6

5x/6  =  60/6

Since the denominators are equal, and these two expressions are equal, then the numerators are equal.

5x = 60

=> 5x/5 = 60/5

=> x = 12

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
