Question

3(x+5)-4(2x-10) = -30

Answer 1

Ответ:

$3(x+5)-4(2x-10) = -30\\\\3x + 15 - 8x + 40 = -30\\\\3x - 8x = -30 - 40 - 15\\\\-5x = -85\\\\x = 17$

Answer 2

To solve the equation 3(x+5) - 4(2x-10) = -30, follow these steps:

1. Distribute the constants (3 and -4) into the parentheses: 3x + 15 - 8x + 40 = -30

2. Combine like terms on both sides of the equation: (3x - 8x) + (15 + 40) = -30 -5x + 55 = -30

3. Next, isolate the variable term (-5x) by subtracting 55 from both sides of the equation: -5x + 55 - 55 = -30 - 55 -5x = -85

4. Finally, divide both sides by -5 to solve for x: (-5x) / (-5) = (-85) / (-5) x = 17

So, the solution to the equation is x = 17.
