Question

(x)(1/15)+(x+1)(1/20)=1

Answer 1

wait im doing this wrong..

Answer 2

x/15 + x/20 + 1/20 = 1
20x/15 + x + 1 = 20
20x/15 +x = 19

Answer 3

(20x + 15x)/15 = 19

Answer 4

35x/15 = 19
7x/3 = 19
7x = 19*3
x = 8.142

Answer 5

satellite check my arithmetic haha..

Answer 6

you can also multiply both sides by 60 to clear the fractions
you will get
\[4x+3(x+1)=60\][
\[7x+3=60\]
\[7x=57\]
\[x=\frac{57}{7}\]

Answer 7

is that the same answer?

Answer 8

Answer 9

ok then it is right. but i like getting rid of fractions to make the arithmetic easier. of course it doesn't matter.
