Answer:

y = 5 and x = -3

Step-by-step explanation:

Given,

y = x + 8 ...............( equation 1 )

x + y = 2 ...............( equation 2 )

Now, by substituting the value of y in equation 2, we get;

⇒ x + x + 8 = 2

⇒ x = -3

and now, by substituting the value of x in equation 1, we get;

⇒ y = -3 + 8

⇒ y = 5

Answer:

Step-by-step explanation:

R(0,0)

A=((0+2a)/2,(0+2b)/2)=(a,b)

S(2a,2b)

B=((2a+2c)/2,(2b+2d)/2)=(a+c,b+d)

T(2c,2d)

C=((2c+2c)/2,(2d+0)/2)=(2c,d)

V(2c,0)

D=((2c+0)/2,(0+0)/2)=(c,0)

R(0,0)

slope of AB=(b+d-b)/(a+c-a)=d/c

slope of DC=(d-0)/(2c-c)=d/c

slope of AD=(0-b)/(c-a)=-b/(c-a)

slope of BC=(d-b-d)/(2c-a-c)=-b/(c-a)

How to solve 4/7y-2 = 3/7 + 3/14

lisabon 2012 [21]

Solution

1) Simplify $\frac{4}{7y}$ <span> to </span> $\frac{4y}{7}$
$\frac{4y}{7}$ <span>−2= </span> $\frac{3}{7}$ + $\frac{3}{14}$

2) Simplify $\frac{3}{7}$ + $\frac{3}{14}$ <span>to <span>914</span>
</span> $\frac{4y}{7}$ <span>−2= </span> $\frac{9}{14}$

3) <span>Add 2 to both sides
</span> $\frac{4y}{7}$ = $\frac{9}{14}$ <span>+2
</span>
4) Simplify $\frac{9}{14
}$ <span><span>+2</span> to </span> $\frac{37}{14}$
$\frac{4y}{7}$ = $\frac{37}{14}$

5) <span>Multiply both sides by 7
</span><span>4y= </span> $\frac{37}{14}$ <span>×7
</span>
6) Simplify $\frac{37}{14}$ <span><span>×7</span> to </span> $\frac{259}{14}$
$\frac{4y}{7}$ = $\frac{259}{14}$

7) Simplify $\frac{259}{14}$ <span> to </span> $\frac{37}{2}$
$\frac{4y}{7}$ = $\frac{37}{2}$

8) <span>Divide both sides by 4
</span>y= $\frac{37}{2}$ <span>×4
</span>
9) <span>Simplify <span>2×4</span> to 8
</span><span>y=</span> $\frac{37}{8}$
<span><span>
Hope this helps
