Hello!
Let's write this as an equation.
3(x+3)=5x-3
First, let's simplify the parentheses.
3x+9=5x-3
Let's subtract 5x from both sides.
-2x+9=-3
We subtract 9 from both sides.
-2x=-12
We divide both sides by -2.
x=6
Therefore, the number is 6.
I hope this helps!

Answer:
134
Step-by-step explanation:
This sequence is arithmetic because it's going up by sane number, 3. Hence, it also linear for the same reason. The equation is y=3x+(0th term). The 0th term is the one before the 1st term, 11, which would be 8.
So the equation to finc any xth term is y=3x+8.
Example, first term is 3(1)+8=11.
Example, second term is 3(2)+8=14.
Example, third term is 3(3)+8=17.
The 42nd term is 3(42)+8=126+8=134.
