Question

how to solve any 3 linear equations simultaneously ??

Answer 1

Question -

(a) 5x - 11 = 3x + 9

(b) 3y + 4 = 7 - 2y

(c) 9 - 2(x - 5) = x + 10

Answer-

(a) 10

(b) 3/5

(c) 3

Solution-

(a)5x - 11 = 3x + 9

2x = 20

x = 10

(b)3y + 4 = 7 - 2y

5y = 3

y=3/5

(c)9 - 2(x - 5) = x + 10

9-2x+10 = x+10

x=3

Hope it help you.
