Question

I.
Elimination Method
2z - 3y + 13 - 0
32 - 2y + 2-0
-- 0
-​

Answer 1

Correct Question

solve the given Equation by elimination method

2z - 3y + 13 =0

3z - 2y + 2=0

Given

• Two Equations.
• 2z - 3y + 13 =0
• 3z - 2y + 2=0

To solve

• Value of z and Y by elimination method

Solution

2z - 3y =-13____(1)

3z - 2y =-2_____(2)

Multiply by (2) in Equation (2) And 3 in (1)

6z - 9y =-39____(3)

6z - 4y =-4_____(4)

_______________

-5y = -35

=>y= 7

Putting the value of y in equation (1)

2z - 3y =-13

=>2z-21=-13

=>2z=8

=>z=4
