Zepler [3.9K]

D+Q=61 => D=61-Q
3+D=Q

10(61-Q) + 25Q=1090
610-10Q+25Q=1090

610+15Q=1090
-610 -610

15Q=480

480/15=32

Substitution

Changing or replacing from a term to another terms/expression is called substitution.

Examples:—

If we are given the expression $\displaystyle \large{2y-1}$ and we want to find the value when y = 4, simply replace y-term to 4.

$\displaystyle \large{2(4)-1=8-1=\boxed{7}}$
