Question

Solve the following simultaneous equations: 4 y - 19 x = 12 ; 4 y + 3 x = 100​

Answer 1

Answer:

On solving , we get 22x=88

so x=4

on substituting x value in any equation we get the required answer

y=22

Answer 2

Subtracting 1 and 2 equation
-22x = -88
x = -4
Put x = -4 in equation 2
4y -12 = 100
4y = 112
y = 29
