Answer 2

Substitution Method -:

☆ 3x + 4y = 5...《Find the x value》

》3x = 5 - 4y

》x = (5 - 4y)/3

☆ 2x + 3y = 3...《Take x value in this eqn to get the value of y》

》2[(5 - 4y)/3] + 3y = 3

》10/3 - 8y/3 + 3y = 3

》(-8y + 9y)/3 = 3 - 10/3

》y/3 = (9 - 10)/3

》y = -1

☆ 2x + 3y = 3...《Now find x value with the help of y value》

》2x + 3(-1) = 3

》2x - 3 = 3

》2x = 6

》x = 3

• The values of x and y are 3 and -1.
