Answer 1

Have you attempted the problem?

Answer 2

yes i used the normal formula but its not doing it right

Answer 3

Can you show me what you have?

Answer 4

-1.475

Answer 5

the parentheses threw me off

Answer 6

Hmm alright there is actually no formula...
\[\huge~\rm~\bf 5(a-4)-8a=55\]
Start by distributing the 5
\[\huge~\rm~(5)(a)+(5)(-4)\]

Answer 7

5a + 1

Answer 8

Multiplying....
5a is correct 1 is not.

Answer 9

5 + -4 right

Answer 10

No
\[\huge~\rm~\bf 5 \times -4\]

Answer 11

ok - 20

Answer 12

good now we have
\[\huge~\rm~\bf 5a-20-8a=55\]
From here combine LIKE TERMS
\[\huge~\rm~(5a−8a)+(−20)\]

Answer 13

-13 + -20

Answer 14

5-8=?

Answer 15

3

Answer 16

5-8=-3
\[\huge~\rm~\bf −3a−20=55 \]
Next step add 20 to both sides
\[\huge~\rm~\bf −3a−20+20=55+20 \]
What are we left with?

Answer 17

-3a = 75

Answer 18

so - 25

Answer 19

Good :)
\[\huge~\rm~\bf −3a=75 \]
Now divide both sides by -3
And you get a=-25 correct =)

Answer 20

great
