Question

2. Solve the following pair of equations
by eliminating method.
2x + y - 5 = 0 ; 3x – 2y - 4 = 0​

Answer 1

Answer:

x=2, y=1

Step-by-step explanation:

2x+y-5=0-›2x+y=5--eq1

3x-2y-4=0-›3x-2y=4--eq2

Multiply eq1 by 3 and eq2 by 2

3×(2x+y=5)-›6x+3y=15--eq3

2×(3x-2y=4)-›6x-4y=8--eq4

Add eq3 and eq4, we get

7y=7

y=7/7

y=1

Substitute y=1 in eq1

2x+y=5

2x+1=5

2x=5-1

2x=4

x=4/2

x=2
