## anonymous one year ago By what number must you multiply each side of the equation 2/3x=10 to produce the equivalent equation x=15 ? A.3/2 B.-2/3 C.3 D.1/3

can you help me @Vocaloid ?

Hint $\large \frac{a}{bx} = c \rightarrow x= \frac{b}{a}(c)$

and then use 10 or 15 to multiply the 2 numbers?

7. johnweldon1993

We are just asked to turn $$\large \frac{2}{3x} = 10$$ into $$\large x = 15$$ So we needed to isolate 'x' which can be done by...? Look at my above post

b/a 15 or b/a 10?

9. johnweldon1993

Compare the two $\large \frac{2}{3x} = 10 \rightarrow \frac{a}{bx} = c$ $\large x = ?$

x=15

11. johnweldon1993

Yes we know that 'x = 15' that is given Look again what I posted, I'll copy it all at once $\large \frac{a}{bx}=c \rightarrow x = \frac{b}{a}(c)$ You have $\large \frac{2}{3x} = 10 \rightarrow x = \frac{?}{?}(10)$
