Question

Solve rhe following equation by elimination method 2xplus 3yis equal to 10 and 4x minus 2y is equal to 4

Answer 1

Answer:

x=2, y=2

Step-by-step explanation:

2x+3y = 10 ---(1) ×2 ⇒ 4x+6y = 20

4x-2y = 4  ---(2)

---

4x+6y = 20

-(4x-2y = 4)

⇒ 4x+6y = 20

   -4x+2y = -4)

-----------------------

    0 +8y = 16

            y = 2

Put y=2 in equation (1),

4x-4=4

4(x-1)=4

x-1=1

x=2
