The intent is to manipulate the equation and arrive with an equation of the form x = "some number". The manipulations must ensure that at every step the relationship remains an equality. The valid manipulations are
My equation is 7 = 4(3  x). I am first going to use the distributive law to multiple (3  x) by 4.
I want the term involving x on the left side of the equation so add 4x to each side
I don't want the 7 on the left side of the equation so subtract 7 from each side.
Finally divide both sides by 4 to get
Now try your equation 5 = 3(x  2). Penny
