Question

Solve 3x + 2y = 11 and 2x + 5y = 8​

Answer 1

Answer:

Solve 3x + 2y = 11 and 2x + 5y = 8 with Elimination Method. - 39712172. ... 11y=13. Now put the value of y in any eq. 3x+2(13/11)=11.

Answer 2

x = 39/11

y = 2/11

Step-by-step explanation:

3x + 2y = 11 ------(1) × 2

2x + 5y = 8 ------(2) × 3

=>

6x + 4y = 22

6x + 15y = 24

-__-_____-__

0 - 11y = -2

y = 2/11

Put value of y= 2/11 in equation (1)

we get,

$3x + 2 \times \frac{2}{11} = 11$

$3x + \frac{4}{11} = 11$

$3x = 11 - \frac{4}{11}$

3x = 121 - 4 /11

3x = 117/11

$x = \frac{117}{11 \times 3} = \frac{39}{11}$
