Cancel x on both sides: 1/5 = -1/2. No solution.

2. JessicaO

These are proportions.. Im supposed to be using cross products.

3. JessicaO

I get a decimal... /:

ok

5. muntoo

$\Large \frac{x+1}{5}={x-1\over2}$ Be more specific next time. Use parenthesis or the equation editor.

6. muntoo

Multiply both sides by $$5\cdot2$$.

Ah, then you should have typed it like: (x+1)/5 = (x-1)/2. Careful with parentheses usage. So, when you cross-multiply (not cross product - that's a vector term), you get: $\dfrac {x+1}{5} = \dfrac {x-1}{2} \rightarrow 2(x+1) = 5(x-1) \rightarrow 2x + 2 = 5x - 5 \rightarrow 3x = -7,$ so you're right. It's a decimal. @goformit100 Spamming != Good. ;) @JessicaO Remember what muntoo and I said - be specific. ;)
