Question

6 (x+2 ) + 3 (3x+7) = 4 ( 5 + 4 x ) -7​

Answer 1

Ответ:

6x +12+9x+21=20+16x-7

15x-16x=13-33

-x=-20

x=20

Answer 2

Let's solve the equation step by step:

6(x + 2) + 3(3x + 7) = 4(5 + 4x) - 7

First, let's simplify each side of the equation:

6x + 12 + 9x + 21 = 20 + 16x - 7

Combine like terms:

15x + 33 = 16x + 13

Next, let's isolate the variables on one side of the equation:

15x - 16x = 13 - 33

-x = -20

To eliminate the negative sign, we can multiply both sides of the equation by -1:

x = 20

Therefore, the solution to the equation is x = 20.
