Subtract 4 from both sides. The four on the left would cancel out and the 13 on the right would now be a 9. Therefore, the answer is
I believe this is what you are looking for friend
3x +7 = x + 15 subtract x from both sides
2x + 7 = 15 subtract 7 from both sides
2x = 8 divide both sides by 2
n+4 ≤ 13
I turned "a number" to a variable which was n. Then it said 4 more
a number (n) is no more than 13. we could represent that as n + 4 ≤ 13. Which basically represents a number plus 4 is less than or equal to 13.
using X for your mystery number, the answer is:
x + 11 · x + 8
just analyze the words carefully and their meanings, ex.: no more than = ≤
if you wish for the answer to this inequality:
x ≤ 9
just subtract 4 from both sides to leave x alone
Let’s set a variable for our unknown number. Let’s have b.
=> b + 5 (b + 2) = 4b + 26
Now, we have our equation, let’s start solving.
=> b + 5b + 10 = 4b + 26
=> 6b + 10 = 4b + 26
=> 6b - 4b = 26 – 10
=> 2b = 16
=> b = 16 / 2
=> b = 8
Thus, the number that Laura is thinking of is 8.
No more than means using < in the equation;
So is your equation.
For the given problem the inequality will be;
x+4<or equal to 13
this is saying any number (x) plus 4 is equal to or less than 13 and this follows the question of 4 more than a number(x) is no more than 13. So it is saying the sum of these two number can equal or be less than 13.
