Question

9(x - 3) - 4(7 – 3x) - 3 = -8x.​

Answer 1

Ответ: 2

Пошаговое объяснение:

9(х-3)-4(7-3х)-3=-8х

9х-27-28+12х-3=-8х

9х+12х+8х=27+28+3

29х=58

х=58:29

х=2

Answer 3

To solve the given equation, let's simplify and solve step by step:

Starting with the given equation: 9(x - 3) - 4(7 - 3x) - 3 = -8x

First, let's simplify the expressions within parentheses: 9x - 27 - 28 + 12x - 3 = -8x

Combining like terms on both sides: 21x - 58 = -8x

Now, let's isolate the variable terms on one side by adding 8x to both sides: 21x + 8x - 58 = -8x + 8x 29x - 58 = 0

Next, let's isolate the constant term by adding 58 to both sides: 29x - 58 + 58 = 0 + 58 29x = 58

Finally, divide both sides by 29 to solve for x: x = 58/29

Simplifying the division: x = 2

Therefore, the solution to the equation 9(x - 3) - 4(7 - 3x) - 3 = -8x is x = 2.
