Question

y-3=2(x+1)y−3=2(x+1) find the missing value

Answer 1

y-3=2(X+1)

or,y-3=2x+2

or,2x-y=-1......(1)

y-3=2(X+1)y

or,y-3=2x+2y

or,2x+y=-3.....(2)

solving both equation

2x-y=-1

-2x+y=-3

.............................

4x=-4

X=-1

putting the value of X in equation 1

-2-y=-1

or,-y=-1+2

=1

or,y=-1

which is the missing values ...
