Answer:

x = 1 1/3 and y = 2 7/9

Step-by-step explanation:

Subtract the two equations:

$5x + 3y = 15\\2x + 3y = 11$

3x = 4

divide both sides by 3

x = 4/3

Substitute this into the equation 5x + 3y = 15

$5(\frac{4}{3} ) + 3y = 15\\\frac{20}{3} + 3y = 15\\3y = 8\frac{1}{3} \\y = 2\frac{7}{9}$

Simplify by combining like terms:<br><br> -5x-13+7y+26x

sveticcg [70]

Answer:

26x and -5x are like terms, so what you would do with these is 26x subtract -5x, which is 21x.

The final expression is:

-13 + 7y + 21x

The only pair of like terms in this expression is 26x and -5x.
