Question

all the pair of equation 3 X + 2y - 13 is equals to zero and 6 x minus 4 Y - 10 is equals to zero by using substitution method​

Answer 1

Question :-

Given above

Answer :-

Let ,

3x +2y -13 = 0 ......eq .(1)

and,

6x - 4y -10 = 0....eq .(2)

From eq.(1)

→3x +2y = 13

→ 3x = 13-2y

→ x=(13- 2y)/3

put in eq .(2)

→ 6(13 - 2y) /3 - 4y -10 = 0

→ 26 - 4y -4y -10 = 0

→ -8y = -16

→ y = 2

put in eq .(1)

→ 3x +2×2 -13 = 0

→ 3x = 9

→ x = 3
