Question

3x/4 * 5/4= 256

what is the value in the variable (x)(what does x equal)

Answer 1

Multiply across

3x * 5 = 15x

1/4 * 1/4 = 1/16

15x/16 = 256

Isolate the x. Note the equal sign. What you do to one side, you do to the other

Multiply 16 to both sides

15x/16(16) = 256(16)

15x = 256(16)

15x = 4096

15x/15 = 4096/15

x = 273.07 (rounded).

273.07 is your answer

hope this helps
