Question

if a number added to 2 and mulplied by 6 the result is 42, then what is the number​

Answer 1

• The number is 5.

Step-by-step explanation:

We are given that a number is added to 2 and mulplied by 6 and the the result is 42.

Let,

• The unknown number be $'x'$

And the equation would be,

• $\sf{x\:+\:2\:\times\:6\:=\:42}$

Solving,

$\implies\sf{x\:+\:2\:\times\:6\:=\:42}$

$\implies\sf{x\:+\:2\:\times\:6\:=\:{\dfrac{42}{6}}}$

$\implies\sf{x\:+\:2\:\times\:6\:=\:{\cancel{{\dfrac{42}{6}}}}}$

$\implies\sf{x\:+\:2\:=\:7}$

$\implies\sf{x\:\:=\:7\:-\:2}$

$\implies\sf{x\:\:=\:5}$

Verifying this by substituting x value :

$\implies\sf{x\:+\:2\:\times\:6\:=\:42}$

$\implies\sf{5\:+\:2\:\times\:6\:=\:42}$

$\implies\sf{7\:\times\:6\:=\:42}$

$\implies\sf{42\:=\:42}$

Hence, the number is 5.
