$x = \frac{y}{m} - a$ $x=y/m-a$

$(x + a) m = y$ $(x+a)m = y$
Expand: $x m + a m = y$ $xm+am=y$

Subtract $a m$ $am$ from both sides:

$x m + a m - a m = y - a m \to x m = y - a m$ $xm+am-am=y-am->xm=y-am$
Divide through by $m : \to$ $m: ->$ $x=y/m-(acancelm)/cancelm$

$x=y/m-a$

How do you solve for xxx in (x+a)m=y(x+a)m=y(x+a)m=y?
