Question

solve the pair of linear equation by elimination method. 3x +4y =10, 2x - 2y =2.

Answer 1

3x+4y=10 (eqn.1), 2x+2y=2(eqn.2)
From eqn.1,
y= 10-3x÷4
Substitute y in eqn.2
2x+2(10-3x÷4)=2
X=-6
Putting x=-6 in y=10-3x÷4 we get y=4

Answer 2

Answer:

hope it helps

Step-by-step explanation:

3x+4y=10 (eqn.1), 2x+2y=2(eqn.2)

From eqn.1,

y= 10-3x÷4

Substitute y in eqn.2

2x+2(10-3x÷4)=2

X=-6

Putting x=-6 in y=10-3x÷4 we get y=4
