Solve the simultaneous linear equation 2x+5y=11, 7x+4y=2​
Andrews [41]

Answer:

x = -\frac{34}{27} and y = \frac{73}{27}

Step-by-step explanation:

2x + 5y = 11

7x + 4y = 2

Let's try elimination here since we have a system of equations:

-7(2x + 5y = 11) = -14x - 35y = -77

and

2(7x + 4y = 2) = 14x + 8y = 4

The <em>x</em>'s cancel out now so let's combine the two equations:

-35 + 8 = -27

-77 + 4 = -73

-27y = -73

y = \frac{73}{27}

Now that we have <em>y</em>'s value, let's plug that value in for <em>y</em> in the other equation. You may choose whichever equation you want to solve for <em>x</em> but it is recommended to use the easiest one. (Since this value is complicated, it won't really matter.)

2x + 5(\frac{73}{27}) = 11

2x + \frac{365}{27} = 11

2x = -\frac{68}{27}

x = -\frac{34}{27}

To check and make sure you have the correct values, plug both values into the orginal equation and make sure the equation is true.

Solve this application problem using a system of equations: The Bright College footballteam scored 80 times last season, some on
Goryan [66]

Answer:

\large \boxed{\sf \ \ 69 \ \textbf{touchdowns } 11 \ \textbf{field goals } \ }

Step-by-step explanation:

Hello,

Touchdown is 7 points, field goals is 3 points

Let's note a the number of touchdowns and b the number of field goals, we can write

   (1)    a + b = 80

   (2)    7a + 3b = 516

(2) - 3*(1) gives

7a + 3b - 3(a + b) = 516 - 3*80

<=> 7a + 3b -3a - 3b = 516 - 240 = 276

<=> 4a = 276

<=> a=\dfrac{276}{4}=69

And then from (1) b = 80 - 69 = 11

Hope this helps
