Mama L [17]3 years ago
7 0

Answer:

{x,y} = {25/9,23/9}

Step-by-step explanation:

// Solve equation [2] for the variable  x  

 

 [2]    x = -4y + 13

// Plug this in for variable  x  in equation [1]

  [1]    5•(-4y+13) + 2y = 19

  [1]     - 18y = -46

// Solve equation [1] for the variable  y  

  [1]    18y = 46  

  [1]    y = 23/9  

// By now we know this much :

   x = -4y+13

   y = 23/9

// Use the  y  value to solve for  x

Which letters from the table represent like terms? A and B B and C A and D B and D.
xenn [34]

The letters can be added together if they have similar variables.

B and C are like terms. Option B shows the like terms of letters.

<h3>What is a binomial?</h3><h3></h3>

A mathematical expression consisting of two terms connected by a plus sign or minus sign is called the binomial expression.

The attachment shows the table of letters and variables.

To multiply binomials, a form of the distributive property is used.

The table has been complete with the final values of letters which are given below.

A= (-2x) \times 4x

A = -8x^2

B = 3 \times 4x

B = 12 x

C = (-2x)\times 1

C = -2x

D = 3\times 1

D = 3

From the final values of letters, B and C are the only like terms, they can be added together since they have similar variables.

Hence we can conclude that B and C are like terms. Option B shows the like terms of letters.

To know more about the binomials, follow the link given below.
