help me which equation shows the variable terms isolated to one side and the constant terms isolated on the other side for the equation -1/2x+3=4-1/4x?

its line 2 i just added the rest or else it wouldn't let me answer

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
