Step-by-step explanation:

\textsf{\large{\underline{Solution}:}}

<h3>Given Equations:</h3>

→ 5x - 2y = 6 ----- (i)

→ 3x + 2y = 10 ---- (ii)

Adding (i) and (ii), we get:

→ 8x = 16

→ x = 16/8

→ x = 2

Substituting the value of x in (i), we get:

→ 5 × 2 - 2y = 6

→ -2y = 6 - 10

→ -2y = -4

→ y = -4/-2

→ y = 2

Therefore:

→ (x, y) = (2, 2) (Answer)

\textsf{\large{\underline{Verification}:}}

Put x = 2 and y = 2 in second equation, the LHS becomes:

= 5 × 2 - 2 × 2

= 10 - 4

= 6

= RHS

Put x = 2 and y = 2 in second equation, the LHS becomes:

= 3 × 2 + 2 × 2

= 6 + 4

= 10

= RHS

Hence, our answer is correct (Verified)

Hope this helps!!

What is the slope of the line show belowww
zaharov [31]

Answer:

\boxed{C.\:\: 2}

Step-by-step explanation:

The given line passes through the points,


(x_1,y_1)=(-2,-3) and (x_2,y_2)=(3,7).


We can find the slope using the following;

m=\frac{y_2-y_1}{x_2-x_1}


or


m=\frac{y_1-y_2}{x_1-x_2}


Using the first formula;


We obtain;

m=\frac{7--3}{3--2}


\Rightarrow m=\frac{7+3}{3+2}


\Rightarrow m=\frac{10}{5}


\Rightarrow m=2


The correct answer is C.

Vamsi is X years old.his brother is 3 years elder to him. his uncle is 4 times his age and his aunt is 5 years younger than his
liberstina [14]

Step-by-step explanation:

<em>Vamsi is X years old</em>

Vamsi = X

<em>his brother is 3 years elder to him</em>

Brother = X + 3

<em>his uncle is 4 times his age</em>

Uncle = 4X

<em>his aunt is 5 years younger than his uncle</em>

Aunt = Uncle - 5

<em>what will be the age of his uncle 6 years from now</em>

= 4X + 6

<em>what are the ages of vamis brother, uncle and aunt?</em>

Assume Vamis = 15 years

Brother = X + 3 = 15 +  3 = 18

Uncle = 4X = 4 * 15 = 60

Aunt = Uncle - 5 = 60 - 5 = 55

<em>what will be the age of his uncle 6 years from now</em>

Uncle = 4X + 6 = 60 + 6 = 66
