Answer 1

Based on the equation given, the value of x and y will be 8 and -4 respectively.

How to get the values?

From the information given,

3x - y = 4 ..... i

x - y = 4 ..... ii

From equation ii x = 4 + y

Put the value of x into equation i

3x - y = 4

3(4 + y) - y = 4

12 + 3y - y = 4

3y - y = 4 - 12

2y = -8

y = -8/2 = -4

Since x - y = 4

x - 4 = 4

x = 4 + 4 = 8

x = 8
