Question

Please help! Thanks!!

Answer 1

a) Equation is: 3x+4=22

b) Solving the equation we get the number x = 6

Explanation:

a) Equation

Let the number be x.

Translating the statement into mathematical form:

Multiply the number with 3 i.e 3x

Add four i.e 3x+4

I get twenty two means: 3x+4=22

So, Equation is: 3x+4=22

b) Solve the equation:

3x+4=22

subtracting 4 on both sides

`3x+4=22\\3x+4-4=22-4\\3x=18`

Divide both sides by 3

`(3x)/(3)=(18)/(3)\\x=6`

So, the number x = 6
