Solve the following equations. 2x - y = 8 3x + y = 17​
aleksley [76]
<h2>Answer: (5, 2)</h2>

<h2>System of equations:</h2>

2x - y = 8

3x + y = 17

<h2>Solve for x:</h2>

2x - y = 8

3x + y = 17

________ +

5x = 25

x = 5

<h2>Plug in x to one of the equations to solve for Y</h2>

2(5) - y = 8

10 - y = 8

-y = -2

y = 2

Need this in 3 mins, 30 points, will mark as Brainliest!!!! Solve:
Sergeeva-Olga [200]

Answer:

The missing number is 4

Step-by-step explanation:

Given

21 x 39 x _____ x 19 divided by 12 = 5187

Required

Fill in the gap

Let the missing number be represented with y; So, the expression becomes

\frac{21 * 39 * y * 19 }{12} = 5187

Multiply both sides by 12

12 * \frac{21 * 39 * y * 19 }{12} = 5187 * 12

21 * 39 * y * 19 = 62244

Rearrange the expression on the left hand side

21 * 39 * 19 * y = 62244

15561 * y = 62244

Divide both sides by 15561

\frac{15561 * y}{15561} = \frac{62244}{15561}

y = \frac{62244}{15561}

y = 4

Hence, the missing number is 4
