Question

x+y=7;3x-2y=11
solve the following simultaneously equation​

Answer 1

Given:-

→x+y=7๛(1)

→3x-2y=11๛(2)

$\rule{200}{1}$

To Find:-

→The Values of x&y?

$\rule{200}{1}$

AnsWer:-

★Multiply Eq-(1) with 3★

→3x+3y=21๛(3)

★Add eq-(3)&(2)★

→3x+3y=21

→3x-2y=11

•Refer Attachment for Addition•

→5y=10

→y=$\frac{10}{5}$

→y=2๛(4)

♦Using (4) in (1)♦

→x+2=7

→x=7-2

→x=5

$\rule{200}{1}$

♠Hence x=5 and y=2♠

$\rule{200}{2}$
