Question

Find the value of : 3x + y - 3 [ When x = 5, y = 7 ]​

Answer 1

Answer:

When x = 5, y = 7   then 3x + y - 3 = 19

Step-by-step explanation:

Find the value of : 3x + y - 3  When x = 5, y = 7  

Put x = 5 and y = 7 in 3x + y - 3, we get

3x + y - 3

=3(5) + 7 - 3

= 15 +7 - 3

= 15 + 4

= 19

3x + y - 3 = 19 when x = 5, y = 7  

Answer 2

Answer:

∴ The value of given equation, $3x+y-3$ at $x=5$ and $y=7$ is $19$.

Step-by-step explanation:

• In context to question asked,
• We have to find the value of $3x+y-3$.
• The values of $x=5$ and $y=7$ is given.
• To find the value of given equation, we have to put $x=5$ and $y=7$ in given equation.
• So, the given equation is,

         $3x+y-3$

• Put $x=5$ and $y=7$ in given equation, we get

     $3x+y-3=3\times 5+7-3$

                   = $15+7-3$

                   = $19$

• ∴ The value of given equation, $3x+y-3$ at $x=5$ and $y=7$ is $19$.
