Answer:
2/3
Step-by-step explanation:
If 2/3 · x= 4/9 then 4/9 ÷ 2/3= x
KCF (Keep Change Flip)
Keep 4/9
4/9 ÷ 2/3
Change from division to multiplication
4/9 · 2/3
Flip 2/3 to 3/2
4/9 · 3/2
Multiply 4 · 3= 12
Multiply 9 · 2= 18
Simplify
12 ÷ 6= 2
18 ÷ 6= 3
x=2/3
First, figure out what you do and don't know....
You do know that 3 times the sum of a number and 4 is 18 more than the number....you don't know the number so you make it the variable x
now take 3 times the sum of a number and 4 and make that an expression 3x+4 this expression is the same or equal to the sum of x and 18 x+18
3x+4=x+18
2x+4=18
2x=14
x=7
hope this helped :)
