7=31​ (8x+3)

The equation you've given is 7 = 31 * (8x + 3). To solve for x, follow these steps:

Step 1: Divide both sides of the equation by 31 to isolate the term in parentheses on the right side of the equation. This gives you:

7/31 = 8x + 3

Step 2: Subtract 3 from both sides of the equation to isolate the term with x on the right side of the equation. This gives you:

7/31 - 3 = 8x

Step 3: Divide both sides of the equation by 8 to solve for x. This gives you:

(7/31 - 3) / 8 = x

You can simplify the left side of the equation to get a decimal or fraction that represents the value of x.
