5x + 7y = 17 x + 4y = 19

Mathematics
1 answer:
REY [17]3 years ago
5 0
<h2>Answer:</h2>

5x + 7y = 17 ....(1)

x + 4y = 19 .....(2)

<u>From equation 2</u>

x + 4y = 19

x = 19 - 4y

<u>Putting the value of x in Equation (1)</u>

5(19 - 4y) + 7y = 17

95 - 20y + 7y = 17

- 20y + 7y = 17 - 95

-13y = -78

y = \frac{78}{13}

y = 6

<u>Now, putting the value of y in equation </u><u>(</u><u>2</u><u>)</u>

x + 4y = 19

x + 4(6) = 19

x + 24 = 19

x = 19 - 24

x = -5

<u>Therefore, the value of y is 6 and value of x is -5</u>
