# Let us solve the

4x – 3y = 18 ………[1]

4y – 5x = - 7 ………[2]

by eq. [1]

4x – 3y = 18

4x = 18 + 3y

………[3]

by eq. [2]

4y – 5x = - 7

5x = 4y + 7

………[4]

on comparing eq. [3] and eq. [4]

90 + 15y = 28 + 16y

y = 62 ………[5]

by using eq. [5] in eq. [3]

………[6]

by eq. [5] and [6]

,

verifying the result by eq. [1]
