You can
put this solution on YOUR website!the first set of equation is:
x + 2y = 7 and 3x + 5y = 17
Multiply EQN(1) by 3 and subtract it from the second equation. We get:
3x + 6y = 21
3x + 5y = 17
===========
y = 4
Substituting in one of the equations we can find the value of x
x + 2(4)= 7
==> x = 7 - 8
==> x = -1
The second set of equations are:
x + 3y = 8 and 4x - 3y = 2
Adding the equations we get:
x + 3y = 8
4x - 3y = 2
===========
5x = 10
==> x =
x = 2
By back substitution we can find the value of y.
2 + 3y = 8
3y = 8 - 2
3y = 6
y =
y = 2
thus the solution
NOTE: If these are not the set of equations then mail me back with the correct set of equations wil send you the answers as soon as possible.
