Question

solve the pair of linear equation by the elimination method and substitution method 3 x - 5 Y - 4=0 and 9x= 2 Y + 7​

Answer 1

Step-by-step explanation:

3x-5Y-4, 9x-2y-7=0

multiply 3 in eqn 2

27x-6y-21

multiply 9 in eq 1

27x-45y-36

by elimination method

39y-15

y =-2.6

put the value of y in eq 1

We can find the value of x
