Follow PEMDAS - but backwards.
(Parenthesis, Exponents. Multiplication, Division, Addition, Subtraction)
First SUBTRACT 5 from each side of the equation...
3x/5 + 5 (- 5) = 20 (- 5)
3x/5 = 15
Next MULTIPLY each side by 5...
3x/5 ( • 5) = 15 (• 5)
3x = 75
The third step if you need is to DIVIDE ...
3x ( / 3) = 75 (/ 3)
x = 25
Well,
if 10 of the questions were worth 5pts. that would equal =50
and if 5 were worth 10pts. that would equal= 50
50 + 50 = 100pys.
