Answer:

  x = 29

Step-by-step explanation:

Follow the directions: substitute 13 for y in the first equation.

  x + 13 = 42

Subtract 13 from both sides of the equation.

  x +13 -13 = 42 -13

  x = 29

A system of equations is shown below: x + 3y = 5 (equation 1) 7x − 8y = 6 (equation 2) A student wants to prove that if equation
eduard

First Let we solve the Original system of equations:

equation (1): x+3y=5

equation (2): 7x-8y=6

Multiplying equation (1) by 7, we get

7x+21y=35                          -->(3)

7x-8y=6                           --> (2)

Subtracting,

29y=29 implies y=1

Thenx=5-3(1)=2

Thus the solution of the original equation isx=2, y=1.

Now Let we form the new equation:

Equation 2 is kept unchanged:

Equation (2):7x-8y=6

Equation 1 is replaced with the sum of equation 1 and a multiple of equation 2:

Equation (1): 8x-5y=11

Now solve this two equations: 8x-5y=11, \\                                                    7x-8y=6

Multiply (1) by 7 and (2) by 8,

56x-35y=77

56x-64y=48

Subtracting,29y=29 implies y=1

Then x=2.

so the solution for the new system of equation is x=2, y=1.

This Show that the solution to the system of equations 8x − 5y = 11 and 7x − 8y = 6 is the same as the solution to the given system of equations

Use the equation to answer the question . x + 9 + 2x = 3x + 11 How many solutions does the equation have? ОА. Ano solutions O so
EastWind [94]

Answer:

No solution

Step-by-step explanation:

Add x and 2x.

3x+9=3x+11

Move all terms containing x to the left side of the equation.

Subtract 3x from both sides of the equation.

3x+9−3x=11

Combine the opposite terms in

3x+9−3x.

Subtract 3x from 3x.

0+9=11

Add 0 and 9.

9=11

Since 9≠11, there are no solutions.
