Which expression is equivalent to 3x/5
a: 15x/20
b: 12x/20
c: 12x/5

12x/20

Step-by-step explanation:

Looking at 3x/5

The expression equivalent is 12x/20

The reason is this

12x/20

If you divide the 12x by 4

It will give you 3x

If you divide 20 by 4

It will give you 5

Therefore, you will still have 3x/5

Another way to look at it is this

3x/5= 0.6x

12x/20= 0.6x

Therefore, the final answer is b which is 12x/20

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
