Multiply the equation 4x - 3y = 10 by 2 to make coefficients of y equal in both the equations.

Add the equation 8x - 6y = 20 and 5x + 6y = -7 to eliminate the coefficients of y.

Substitute 1 for x in the equation 5x + 6y =-7 to obtain the value of y.

So solution of equation is (1.-2).
Answer: (1,-2)
