Solve for x.<br> 3х - 4 = 13

dybincka [34]

$\large\bold{\underline{\underline{ \: x = 5 \frac{2}{3} }}}$

$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

$3x - 4 = 13$

$➺ \: 3x = 13 + 4$

$➺ \: 3x = 17$

$➺ \: x = \frac{ 17}{3}$

$➺ \: x = 5 \frac{2}{3}$

$\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}$

$➺ \: 3x - 4 = 13$

$➺ \: 3 \times 5 \frac{2}{3} - 4 = 13$

$➺ \: 3 \times \frac{17}{3} - 4 = 13$

$➺ \: 17 - 4 = 13$

$➺ \: 13 = 13$

➺ L. H. S. = R. H. S.

Hence verified.

C is the correct answer because the question asks for per hour meaning that the amount of toys would be on the top of the fraction over hour. 45 minutes is 3/4 of an hour. per means over or division. so toys divided by hour.
