7x=54+37
7x=91
x=91:7
x=13

Answer 3

To solve the equation (7x - 54) * 39 = 1443, we can follow these steps:

1. Distribute the 39 to the terms inside the parentheses: 7x * 39 - 54 * 39 = 1443

2. Simplify the equation: 273x - 2106 = 1443

3. Move the constant term (-2106) to the other side by adding it: 273x = 1443 + 2106 273x = 3549

4. Divide both sides of the equation by 273 to solve for x: x = 3549 / 273 x ≈ 13.00

Therefore, the solution to the equation is x ≈ 13.00.
