What would be the exact side length of a square if the area was 49 m2

7

Step-by-step explanation:

x = 5

Step-by-step explanation:

First, divide both sides by -5, because both sides are multiplied by -5. This gives you 1 + 2x = x + 6.

Next, subtract x from both sides, and subtract `1 from both sides. This will mean that the x's are all on one side and the number values are on the other, so x = 5.
