3 0

If there is a porpotional relationship then it there will be a pattern like, 7, 14, 21 etc. You can tell because the line will go straight in a perfect line and won't go at a different andle from the rest of the line.

Answer:

Therefore the Final Solution is

x = 2 and y = 4

( 2 , 4 )

Step-by-step explanation:

Given:

$y=2x$ ...............Equation ( 1 )

$x=-y+6$ ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Substitute Equation ( 1 ) in Equation ( 2 ) we get

$x=-2x+6\\\\3x=6\\\\3x=6\\\\x=\frac{6}{3} \\\\\therefore x =2$

Now Substituting x = 2 in Equation ( 1 ) we get

$y =2\times 2\\\\\therefore y=4$

Therefore the Final Solution is

x = 2 and y = 4

( 2 , 4 )

(2x + 3y) + (4x - 3y) = 11+(-5)

Maurinko [17]

Answer:

The correct option should have been $6x=6$ .

Step-by-step explanation:

Given the expression

$\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)$

solving the expression

$\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)$

Remove parentheses: (a) = a

$2x+3y+4x-3y=11-5$

Group like terms

$3y-3y+2x+4x=11-5$

Add similar elements

$6x=6$

It is clear that not a single given option is $6x=6$ . It means no option is correct. It seems you mistyped the correct options.

The correct option should have been $6x=6$ .
