3/4 (x +21) = 10 1/2<br> What does x equal?

Elena L [17]

Answer:

$\huge \boxed{ \boxed{ \red{x = - 7}}}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

$\sf distribute : \\ \frac{3 x+ 63}{4} = 10\frac{1}{2}$
$\sf simplify \: mixed \: fraction : \\ \frac{3x + 63}{4} = \frac{21}{2}$
$\sf cross \: multipication : \\ 2(3x + 63) = 84$
$\sf distribute \: 2 : \\ 6x + 126 = 84$
$\sf cancel \: 126 \: from \: both \: sides : \\ 6x + 126 - 126 = 84 - 126 \\ 6x = - 42$
$\sf divide \: both \: sides \: by \: 6 : \\ \frac{6x}{6} = \frac{ - 42}{6} \\ \bcancel{\frac{6x}{6} } = \frac{ \cancel{ - 42} \: ^{ - 7} }{ \cancel{ \: 6}} \\ \therefore \: x = - 7$

4(x-5) +2 =x+3 <br><br> I need help on this ! I don’t get it picture above !

algol [13]

Answer:

x=-5

Step-by-step explanation:

4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).

4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.

4x-18=x-3 Subtract x from each side. Now, we can get x to only one side.

<u>-x -x</u>

3x-18=-3 Add 18 to both sides.

<u>+18 +18</u>

3x=-15 Divide both sides by 3.

<u>/3 /3</u>

x=-5

I hope this helped you!! Have a great day c:
