Question

8(3,5-1,5х)=35-1,5(7+2х)

Answer 1

Розкриваємо дужки:
28-12х=35-10,5-3х
-12х+3х=35-10,5-28
-9х=-3,5
х=35/90=7/18

Answer 2

To solve the equation 8(3.5 - 1.5x) = 35 - 1.5(7 + 2x), follow these steps:

1. Distribute the 8 on the left side of the equation and the -1.5 on the right side:

   28 - 12x = 35 - 10.5 - 3x

2. Move all the terms containing x to one side of the equation and the constants to the other side:

   -12x + 3x = 35 - 10.5 - 28

3. Combine like terms on each side:

   -9x = -3.5 - 28

4. Subtract 28 from both sides:

   -9x = -31.5

5. Finally, divide both sides by -9 to isolate x:

   x = -31.5 / -9 x = 31.5 / 9 x = 3.5

So, the solution to the equation is:

x = 3.5
