Answer:
a) Equation is: 3x+4=22
b) Solving the equation we get the number x = 6
Step-by-step 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
[tex]3x+4=22\\3x+4-4=22-4\\3x=18[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{18}{3}\\x=6[/tex]
So, the number x = 6
