1). 3x + 7 = 9 2). -3(x + 5) + 3 = 12 Can you also please show the work so that I may have a better understanding.

1). 3x + 7 = 9 subtract 7 from both sides 3 x = 2 divide both sides by 3 x = 2/3 2). -3(x + 5) + 3 = 12 subtract 3 from both sides -3(x+5) = 9 divide both sides by -3 x+5 = -3 subtract 5 from both sides x = -8

so easy

i don't know what to do
