An online seller's rating went down by 2.5. Now the seller's rating is 2.98.
solve your equation for to find the seller's rating before it went down.
Let x be the seller's rating before it went down.
The equation to represent the situation is:
x - 2.5 = 2.98
To solve for x, add 2.5 to both sides of the equation:
x = 2.98 + 2.5
x = 5.48
Therefore, the seller's rating before it went down was 5.48.
