Solve for x: 4x - 8 = 7x - 2<br>Anyone know the answer for this one?<br>Thanks!

erastovalidia [21]

Answer:

$\huge{ \fbox{ \tt{x = - 2}}}$

Step-by-step explanation:

$\underline{ \underline{ \mathfrak{Let's \: solve}}} :$

$\star{ \sf{ \: \: 4x - 8 = 7x - 2}}$

$\text{Step \: 1} : \sf{Move \: 7x \: to \: left \: hand \: side \: and \: change \: its \: sign}$

$\mapsto{ \sf{4x - 7x - 8 = - 2}}$

$\text{Step \: 2} : \sf{Move \: 8 \: to \: right \: hand \: side \: and \: change \: its \: sign}$

$\mapsto{ \sf{4x - 7x = - 2 + 8}}$

$\text{Step \: 3} : \sf{Collect \: like \: terms}$

$\sf{Like \: terms \: are \: those \: which \: have \: same \: base}$

$\mapsto{ \sf{ - 3x = - 2 + 8}}$

$\text{Step \: 4} : \sf{Calculate}$

$\underline{ \text{Remember!}} : \sf{The \: negative \: and \: positive \: integers \: are \: always \: subtracted \: but \: posses \: the \: sign \: of \: the \: bigger \: integer.}$

$\mapsto{ \sf{ - 3x = 6}}$

$\text{Step \: 4} : \sf{Divide \: both \: sides \: by \: - 3}$

$\mapsto{ \sf{ \frac{ - 3x}{ - 3} = \frac{6}{ - 3}}}$

$\text{ Step \: 4} : \sf{Calculate}$

$\mapsto{ \sf{x = - 2}}$

Hope I helped!

Best regards! :D

13.<br> а/8 = $1.25<br> Can someone help explain

Lorico [155]

Answer:

a= $10.00

Step-by-step explanation:

It's very simple. Move /8 to the other side of the equation. It should give you $1.25 x 8. Solve the multiplication and you should get $10.00.

If I didn't make my explanation clear enough, please comment. I sometimes don't even explain myself very well.
