The cost of old computer is $ 357
<em><u>Solution:</u></em>
Let "x" be the cost of old computer
From given,
Cost of new computer = $ 709
Blairs new computer cost 5$ less than twice the cost of her old computer
Therefore,
Cost of new computer = twice the cost of old computer - 5
Cost of new computer = 2x - 5
709 = 2x - 5
2x = 709 + 5
2x = 714
Divide both sides by 2
x = 357
Thus the cost of old computer is $ 357

a(b+c)=ab+ac
we have
3a+7+2(3+a)
distribute first
2(3+a)=6+2a
now we have
3a+7+6+2a
move like terms together
3a+2a+7+6
add lke terms
5a+13
