Answer 2

Step-by-step explanation:

• GIVEN THAT •

________________________________

✓ first equation :-

3x + 2y = 13 --------------------(1)

✓ second equation :-

4x + 5y = 8 --------------------- (2)

________________________________

• TO FIND •

✓ The value of "x" and "y" to solve above both equation

• SOLUTION •

3x + 2y = 13 ------------(1) × 4

12x + 8y = 52 -------------(3)

✓ 4x + 5y = 8 -------------(2) ×3

2x + 15y = 24. -----------(4)

______________________________

✓Now Substracting (3) equation from (4) equation........

________________________________

we got

✓

$7y = - 28 \\ = > y = \frac{ - 28}{7} = - 4$

______________________________

✓™ Now putting the value of y in equation

(1).......

________________________________

$3x + 2( - 4) = 13 \\ = > 3x - 8 = 13 \\ = > 3x = 13 + 8 \\ = > x = \frac{21}{3} = 7$

• CONCLUSION •

✓™ The value of x = 7

✓™ The value of y = -4
