Question

X + y = 6 x - y = 8 Solve the system of equations.

Answer 1

The answer to this question is y=-1

Answer 2

x=7

y=-1

Explanation:

When the two equations are solved together, they form simultaneous equations.

x+y=6

x-y=8

Let us use the elimination method. if we add the two equations, we eliminate y.

2x=14

x=7

Let us substitute for the value of x obtained above.

x-y=8

7-y=8

y=7-8

y=-1
