Question

A)3(8x-6)=(6x-4,5) б)3(5x-7)=5(3x+4)

Answer 1

Ответ:

Объяснение:

a)3(8x-6)=4 (6x-4,5)

24х-18=24х-18

24х-24х=-18+18

0х=0

х=корней нет

б)3(5x-7)=5(3x+4)

15х-21=15х+20

15х-15х=20+21

0х=41

Answer 2

To solve the given equations, let's simplify and find the value of 'x' in each case:

a) 3(8x - 6) = (6x - 4.5)

Step 1: Distribute the 3 on the left side of the equation: 24x - 18 = 6x - 4.5

Step 2: Move all the terms with 'x' to one side of the equation and the constant terms to the other side: 24x - 6x = 18 - 4.5 18x = 13.5

Step 3: Solve for 'x': x = 13.5 / 18 x = 0.75

b) 3(5x - 7) = 5(3x + 4)

Step 1: Distribute the 3 on the left side and the 5 on the right side of the equation: 15x - 21 = 15x + 20

Step 2: Move all the terms with 'x' to one side of the equation and the constant terms to the other side: 15x - 15x = 20 + 21 0 = 41

In this case, the equation simplifies to 0 = 41, which is not true. It means that there is no value of 'x' that satisfies this equation. There might have been an error in the original equation or during the simplification process.

So, the solution to the first equation is: x = 0.75

And the second equation has no solution as it results in a contradiction (0 = 41).
