Question

linear equation in one variable 2 Y + 9 is equal to 4 with its checking​

Answer 1

Answer:

2Y+9=4

=>2Y+9-9=4-9

=>2Y= -5

=>Y= -5/2

checking:

2 * (-5/2) +9

= -5 +9

=4

Therefore LHS=RHS(proved)

☆ ANSWER:-

▪︎ Given linear equation:-

$\tt\leadsto2y + 9 = 4.$

▪︎ To Find:-

• The value of y.

$\rule{400}2$

▪︎ Things you should know:-

• If any number or variable is transported RHS to LHS or vice versa then its symbol also changes.

• i.e. (+) becomes (-).
• (-) becomes (+).
• (×) becomes (÷)
• (÷) becomes (×)

$\rule{400}2$

▪︎ So lets solve the given equation:-

$\sf \mapsto2y + 9 = 4 \\ \\ \sf \mapsto2y = 4 - 9 \\ \\ \sf \mapsto2y = - 5 \\ \\ \sf \large\pink{\fbox{\mapsto \: y = \frac{ - 5}{2}}}$

${\small{\green{\boxed{\tt{\therefore{The\:value\:of\:y\:=\:-5/2.}}}}}}$

$\rule{400}4$

☆ VERIFICATION:-

• To verify that if the value of y is correct or not let us put the value of y which we have obtained in the given equation.

$\tt\mapsto2y + 9 = 4 \\ \\ \tt\mapsto\cancel2( \frac{ - 5}{\cancel{2} }) + 9 = 4 \\ \\ \tt\mapsto - 5 + 9 = 4 \\ \\ \tt\large \red{\fbox{\mapsto4 = 4}}$

• Clearly we can see that RHS = LHS.
