Пошаговое объяснение:

-35+5x-12x+20=0

-7x=15

x= -15/7 = -2 целых 1/7

Answer 3

To solve the expression, you need to apply the distributive property and combine like terms. Let's simplify step by step:

1. Distribute the numbers outside the parentheses: -5(7 - x) = -35 + 5x -4(3x - 5) = -12x + 20

2. Combine the simplified expressions: -35 + 5x - 12x + 20

3. Combine like terms by adding or subtracting coefficients of x: (5x - 12x) = -7x

4. Combine the constants: -35 + 20 = -15

The final expression is: -7x - 15
