Answer 1

Hence, the equation for the question (7) is $n + 19 = 84$ and equation for (8) is $3n = 12$. 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 $ax+b = 0$. Here, $a$ and $b$ are constants and $x$ 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.

$n + 19 = 84$

(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.

    $3n = 12$

Hence, the equation for the question (7) is $n + 19 = 84$ and equation for (8) is $3n = 12$.
