Answer 2

QueStion:-

✦ Write equations for the following statement -

a) The sum of numbers x and 4 is 9.

b) seven times m plus 7 gets you 77

AnswEr:-

a) The sum of numbers x and 4 is 9.

➟ x + 4 = 9 ★

⛤ If we further solve this we get,

➟ x = 9 - 4

➟ x = 5

b) seven times m plus 7 gets you 77

➟ 7 × m + 7 = 77

➟ 7m + 7 = 77 ★

⛤ If we further solve this we get,

➟ 7( m + 1) = 77

➟ m + 1 = $\sf \cancel{ \dfrac{77}{7}}$

➟ m + 1 = 11

➟ m = 11 - 1

➟ m = 10

$\dag$ Hence, we gets both equation and Their solution also.

✶ NOTE:

Both equations are linear equation in one variable.

So, they have only one solution.
