Question of lineear eqyation 10rh class
X+y=8 & x-y=-2

Answer 1

Answer:

Step-by-step explanation: you can solve this equation by using substitution method.

i.e. x+y=8 --- eq 1

x-y=-2----eq 2

Solving eq 1;

X + y = 8

X = 8- y--- eq i

Substituting eq I in eq2

X -y= -2

(8-y)-y=-2

8-y-y=-2

8-2y= -2

-2y=-2-8

-2y=-10

Y= 5

Therefore..

x+y=8

X+5=8

X=3
