Question

• solve the following pair of
linear equations by the
Substitution method ;
A) x+y = 14 and x - y= 4
B) x ÷3 +y÷2=3 and x-2y=2
​

Answer 1

Answer:

A x=9 and y=5

B x=6 and y=2

Answer 2

Answer:

A) from equation 1 - x=14-y

put it in equation 2- then 14-2y=4

2y=10

y=5 and x= 9

B) in equation 1 put x=2+2y

now lcm of 2 and 3 and solve you will get the ans
