3(5x+2)=8x+20
15x+6=8x+20
15x-8x=20-6
7x=14
then you divide both sides by 2
The answer is 2.
so maybe 6 plus 3 which equals 9. Then add 8 at the end
Answer: Your answer would be 16y² + 12x - 4y
so john is x and if Maya has the same as john but -3 then
x+x-3
but sam is still missing and she has half of Maya which is 0.5x - 1.5
so the equation is
x+x-3+0.5x-1.5=68
and then you add 3 and 1.5 to 68 which is
2.5x=72.5
and you divide by 2.5 which is 29
John has 29 points
