and
are (x, y) respectively (5, 3).
Step-by-step explanation:
The given is,
Step:1
By using the elimination method for the above equations are,
Multiply the equation (2) by 2 ( Eqn(2) × 2)
Step:2
Subtract the Equation (1) and (3),
( - )
(
-
) + (
-
) = (
-
)
Step:3
Substitute the value of y in Eqn (2),
Step:4
Check for solution,
Substitute the x and y values in Eqn (1),
(2 × 5) - (5 × 3) = -5
10 - 15 = -5
-5 = -5
Result:
The solution for the equations
and
are (x, y) respectively (5, 3).
