Answer:

Step-by-step explanation:

Given the simultaneous equation we are to find the values of x and y

3x-2y = 14 ..... ×1

5x-y = 32...... ×2

Using elimination method, the equation becomes

3x-2y = 14

10x-2y = 64

.subtract

3x-10x = 14-64

-7x = -50

x = -50/-7

x = 7 1/7

Substitute x = 50/7 into eqn 2

From 2;

5(50/7)-y = 32

250/7 - y = 32

y = 250/7-32

y = (250-224)/7

y = 26/7

Hence (x,y) = (50/7, 26/7)
