Which equations are equivalent to -1/4(x)+3/4=12 select all that apply

1.(-4x/1)+3/4=12

2.-1(x/4)+3/4=12

3.-x+3/4=12

4.1/4(x+3)=12

5.(-x/4)+3/4=12

2, 5

Step-by-step explanation:

Simplify the equation in the question into -x/4+3/4=12 or (-x+3)/4=12

The first option: (-4x/1)+3/4=12

Clearly not the ans since the x is in the denominator

The option 2: -1(x/4)+3/4=12

-1(x/4)+3/4=12 is equal to -x/4+3/4=12

The option 3: -x+3/4=12

Also wrong because it doesn't has the fraction 1/4 so it could multiply with the -x =) -x/4

The option 4: 1/4(x+3)=12

If you notice the fraction 3/4 and 1/4 have the same denominator so you can combine them together into (1+3)/4 but this one, it doesn't give the equivalent equation like the one I solved above because

1/4(x+3) =12

=) x/4 +3/4 =12 (the fraction x/4 is positive)

The option 5: (-x/4)+3/4=12

It's exactly the same equation that I've solved above
