Answer:
A pair of simultaneous equations.
3x + 5y = 9 …………eqn. (i)
5x + 3y = 7 …………..eqn. (ii)
Solving a pair of simultaneous equations, using the elimination method
3x + 5y = 9 …………eqn. (i) x 5
5x + 3y = 7 ……… eqn. (ii) x 3
15x + 25y = 45 ……….. eqn. (iii)
15x+ 9y = 21 …………… eqn. (iv)
Subtract eqn. (iv) from eqn. (iii)
16y = 24
y = 24/16 = 1.5
Substitute y into equation (iv)
15x + 9(1.5) = 21

Step-by-step explanation:
3x -5y = 6
2x -3y= 73
6x - 10y = 12
6x -9y = 219
y= -207
x= 347
