Question

5x+6y=17
6x+5y=16
also find m if y=mx+5 ​

Answer 1

Step-by-step explanation:

5x + 6y = 17_____1

6x + 5y = 16_____2

Adding equations 1 and 2

11x + 11y = 33

x + y = 3______3

Subtracting equations 1 and 2

-x + y = 1________4

Adding eq. 3 and 4,

x + y = 3

-x + y = 1

2y = 4

y = 2

Putting value of y in eq. 3

x + y = 3

x + 2 = 3

x = 1

Value of m

y=mx+5

2 = m×1 + 5

2 = m + 5

m = -3

Hope it helps.
