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>

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

Identify a possible first step using the elimination method to solve the system and then find the solution to the system. 3x - 5

Nastasia [14]

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

3x - 5y = - 2 → (1)

2x + y = 3 → (2)

Multiply (2) by 5 will eliminate y when added to (1), that is

10x + 5y = 15 → (3)

Add (1) and (3) term by term

(3x + 10x) + (- 5y + 5y) = (- 2 + 15)

13x = 13 ( divide both sides by 13 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

2 + y = 3 ⇒ y = 3 - 2 = 1

Solution is (1, 1)
