Question

please give me ans step by step please ​

Answer 1

Step-by-step explanation:

5x+7y=17________eqn (1)

3x-7y=15________Eqn(2)

adding eqn (1)&(2)

5x+7y=17

3x-7y=15

________

8x =32

x=32/8

x=4

puting value x=4 in eqn (1)

5×4+7y=17

7y=17-20

y= -3-7

y= -10

(x, y) (4,-10)

Answer 2

Question:-

Solve the given simultaneous equations

$5x + 7y = 17 ; 3x - 7y = 15$

Solution:-

Refer to the attachment

The value of x is 4

The value of y is$\frac{ - 3}{7}$
