Question

Solve the following pair of linear equations:
3x-5y = 4,2y + 7 = 9x​

Answer 1

Answer:

x= -13/27

y= -5 /3

Step-by-step explanation:

3x-5y=4 ------1

9x-2y=7 -------2

multiplying 1 eqn by 3,

9x-15y=12 ------3

2 eqn - 3 eqn ,

3y= -5

y=-5/3

substituting y in any of the equations,

we get x= -13/27
