Question

if 2x+y - 5=0 and 3y+2y-8 = 0, then findbthe value of x+y.
​

Answer 1

SOLUTION

GIVEN

2x + y - 5= 0 and 3x + 2y - 8 = 0

TO DETERMINE

The value of x and y

EVALUATION

Here the given system of equations are

2x + y - 5= 0 - - - - - (1)

3x + 2y - 8 = 0 - - - - (2)

Multiplying Equation 1 by 2 we get

4x + 2y - 10 = 0 - - - - - (3)

Equation 3 - Equation 2 gives

x - 2 = 0

⇒ x = 2

From Equation 1 Putting the values of x we get

( 2 × 2 ) + y - 5 = 0

⇒ 4 + y - 5 = 0

⇒ y - 1 = 0

⇒ y = 1

FINAL ANSWER

Hence the required solution is

x = 2 & y = 1
