Quick question: I am stumped for some reason my brain is not working today...  How do I figure this out.. x+3/10=-3/5

anonymous · Answer

Assuming this is..

$$\frac{ (x+3) }{10 } = \frac{ -3 }{ 5 }$$
Then cross multiply, to get...

$$5(x+3) = -30$$
Multiply the 5 through the bracket...

$$5x + 15 = -30$$
Subtract 15 off both sides...

$$5x = -45$$
Divide both sides by 5

$$x = -9$$
As a check plug x = -9 into the original equation and you will see that indeed 

$$L.H.S = \frac{ (-9 + 3) }{ 10 } = \frac{ -6 }{ 10 } = \frac{ -3 }{ 5 } = R.H.S$$

L.H.S is referring to the Left Hand Side of the equation, and R.H.S to Right Hand Side of the equation...
