Question

Tell me the answer. the correct answer.​

Answer 1

Answer:

Option A is correct.

Step-by-step explanation:

When we add 4 to both sides of y = 6 it becomes,

y+4 = 6+4 => y+4= 10

Answer 2

Answer:

3x+4y=10 …………..(1)

2x−2y=2 (or) x−y=1 …………(2)

(1) ⇒(3x+4y=10)1

(2) ⇒(x−y=1)3

_____________________

3x+4y=10

3x−3y=3

_____________________

7y=7

∴y=1

Put y=1 in (1) we get 3x+4×1=10

3x=10−4=6

∴x=

3

6

=2

Hence x=2,y=1.
