logan isn't 2 years older than Lindsey. Five years ago the sum of their ages was 30. Find Lindsey current age. X-5+2x-5=30.

-1 + 0= 30. I don't think this right I tried I can't get the right answer. According to the common core the answer is supposed to be 19. Please help I tried but can't get the answer. I really need the answer before Thursday thank you so much.

If you meant that Logan is twice as old as Lindsay, then you are correct in setting it up as you did. Your solution, however, is bogus.

x-5 + 2x-5 = 30
3x - 10 = 30
3x = 40
x = 40/3

No joy there.

If it should have read Logan is 2 years older than Lindsay, then the equation is

(x-5)+(x+2-5) = 30
2x-8 = 30
2x = 38
x = 19

Your assertion that Logan isn't 2 years older than Lindsey does not provide any useful information

im so confused

To solve this problem, let's break it down step by step.

1. Let's define our variables:
Let L be Lindsey's current age.
Let G be Logan's current age.

2. The first sentence tells us that Logan is not 2 years older than Lindsey. This can be expressed as:
G ≠ L + 2

3. The second sentence states that five years ago, the sum of their ages was 30. So, let's create an equation using this information:
(L - 5) + (G - 5) = 30

4. Simplify the equation:
L - 5 + G - 5 = 30
L + G - 10 = 30

5. Rearrange the equation:
L + G = 40

6. Now we have a system of two equations:
G ≠ L + 2
L + G = 40

To find Lindsey's current age, we need to solve this system of equations.

There are multiple ways to solve this system, but let's use substitution.

7. Solve the first equation (G ≠ L + 2) for G:
G = L + 2

8. Substitute G in the second equation (L + G = 40) with L + 2:
L + (L + 2) = 40
2L + 2 = 40
2L = 40 - 2
2L = 38

9. Divide both sides of the equation by 2 to solve for L:
L = 38 / 2
L = 19

Therefore, Lindsey's current age is 19 years old.
