Solve the system of equation by the addition method x-2y=11 and -x+6y =-31
Sonbull [250]

Answer: x = 1, y = - 5

Step-by-step explanation:

The given system of linear equations is expressed as

x - 2y = 11- - - - - - - - - - - - -1

- x + 6y = - 31- - - - - - - - - - - -2

We would eliminate x by adding equation 1 to equation 2. It becomes

- 2y + 6y = 11 - 31

4y = - 20

Dividing the the left hand side and the right hand side of the equation by 4, it becomes

4y/4 = - 20/4

y = - 5

Substituting y = - 5 into equation 1, it becomes

x - 2 × - 5 = 11

x + 10 = 11

Subtracting 10 from the left hand side and the right hand side of the equation, it becomes

x + 10 - 10 = 11 - 10

x = 1

The table summarizes the scoring of a football game between Team A and Team B. A touchdown (TD) is worth 6 points, a field goal
Anit [1.1K]
If you would like to find the final score, you can do this using the following steps:

Team A: 6 points * 3 + 3 points * 2 + 2 points * 1 + 1 point * 0 = 6 * 3 + 3 * 2 + 2 * 1 + 1 * 0 = 18 + 6 + 2 + 0 = 26 points
Team B: 6 points * 4 + 3 points * 4 + 2 points * 1 + 1 point * 2 = 6 * 4 + 3 * 4 + 2 * 1 + 1 * 2 = 24 + 12 + 2 + 2 = 40 points

The final score of team A is 26 points and the final score of team B is 40 points.

Find value of X! Please answer correctly !!!!!!!!!!!!!! Will mark brainliest !!!!!!!!!!!!!!
Amiraneli [1.4K]

Answer:

x = 18

Step-by-step explanation:

By the rule of Consecutive Interior Angles which define what these angles are, they both will add up to 180. As such we can put the sum of these two angles set equal to 180, and solve algebraically

(8x - 20) + (3x + 2) = 180

  8x - 20 + 3x + 2 = 180

                 11x - 18 = 180

                <u>      + 18    +18</u>

                         11x = 198                                                                                                                        

                            x = 198/11

                            x = 18
