#7 ive fallen and i️ cant get ! 0.1(x+20)+0.1x=3 what’s the solution set? ?

The person above is correct. The solution is 5 :)

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
