I need help on my warm up!! pls thx!
xxMikexx [17]

Step-by-step explanation:

\tt{30.16 = 17.56 + 5x}

Swap the sides of the equation :

⤑ \tt{17.56 + 5x = 30.16}

We want to remove the 17.56 first.

Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :

⤑ \tt{5x + 17.56 - 17.56 = 30.16 - 17.56}

Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.

⤑ \tt{5x = 12.6}

Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.

⤑ \tt{ \frac{5x}{5}  =  \frac{12.6}{5}}

Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

\pink{ \boxed{ \boxed { \tt{Our \: final \: answer :  \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ

5.5 = -2 + d
TEA [102]
The value of <em>d</em> is 7.5.

The key to solving equations is doing the inverse, or opposite, function/process.
For example, you subtract when d + 1 = 2:
d + 1 = 2
(d + 1) -1 = (2) - 1
d = 1

In the same way, you add values when you have a negative:
5.5 = -2 + d = d - 2
5.5 = d - 2
(5.5) + 2 = (d - 2) + 2
7.5 = d

Now if instead of adding 2, you subtract 2, the problem becomes:
5.5 = d - 2
(5.5) - 2 = (d - 2) - 2
3.5 = d - 4

This doesn't solve your problem, it just makes the value needed to be canceled out larger.

Thus d = 7.5 and you will add because the value is negative.
