Answer 1

(a) When 4 is subtracted from 7 times $a$, you get 32
7$a$ - 4 = 32

(b) 3 is 7 more than two fifths of $y$.

$\left(\frac{2}{5}\right)$$y$ + 7 = 3

(d) 8 times a number $x$ is equal to three more than 5 times the same number.
8$x$ = 3 + 5$x$

(e) 3 less than 4 times a number $y$ is 5 more than twice the same number.
4$p$ - 3 = 5 + 2$p$
