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 $3n = 12$ .

8(y+4)=7y+38 asap pls

Readme [11.4K]

Distribute
remember a(b+c)=ab+ac
8(y+4)=8(y)+8(4)=8y+32

8y+32=7y+38
minus 7y both sides
y+32=38
mius 32 oth sides
y=6

Math 7a using number sense to solve equations

Anika [276]

Simple...

you have: $\frac{n}{3} =12
$

and

$\frac{n}{3} =-12$

To solve for.... $\frac{n}{3} =12$

Multiply to remove the denominator-->>

$3* \frac{n}{3} =12*3$

n=12*3

n=36

Then-->>>

$\frac{n}{3} =-12$

Do the same thing-->>

$3* \frac{n}{3} =-12*3$

n=-12*3

n=-36

Thus, your answer.
