Hence, the equation for the question (7) is
and equation for (8) is
. It can be solved by linear equation in one variable.
What is a linear equation in one variable?
A linear equation in one variable is written as
. Here,
and
are constants and
is a variable.
(7)
Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.
(8)
Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.

Hence, the equation for the question (7) is
and equation for (8) is
.
