O 5​

Answer 1

Question:-

If in the equation x + 2y =10, the value of y is 6, then the

value of x will be _______.

a)-2

b)2

c) 4

d) 5

Answer:-

• The value of x is -2.

Given:-

• The value of y = 6

To find:-

• The value of y

Solution:-

$\implies \: x + 2y = 10 \\ \\ \implies \: x + 2 \times 6 = 10 \\ \\ \implies \: x + 12 = 10 \\ \\ \implies \: x = 10 - 12 \\ \\ \implies \: x = - 2$

• The value of x is -2.

Hence,

The correct option is (a).

Answer 2

ɢɪᴠᴇɴ :-

• The equation "x+2y=10"
• The value of y = 6

ᴛᴏ ꜰɪɴᴅ :-

• The value of y

ꜱᴏʟᴜᴛɪᴏɴ :-

$\begin{lgathered}:\implies\tt \: x + 2y = 10 \\ \\ :\implies \tt\: x + 2 \times 6 = 10 \\ \\ :\implies \tt\: x + 12 = 10 \\ \\ :\implies\tt \: x = 10 - 12 \\ \\ :\implies \tt\: x = - 2\end{lgathered}$

Hence, the value of x is (-2)

$\begin{lgathered}\begin{lgathered}\begin{lgathered}\begin{lgathered}:\implies{\boxed{\frak{\pink{option\;a\;is\;correct}}}}\;\bigstar\\ \\\end{lgathered}\end{lgathered}\end{lgathered}\end{lgathered}$
