Answer 1

7-2х-15х+6=47
-2х-15х=47-6-7
-17х=34
х=-2
Відповідь: -2))

Answer 2

To solve the equation 7 - 2x - 3(5x - 2) = 47, you'll need to follow these steps:

1. Distribute the -3 on the left side of the equation to eliminate the parentheses:

7 - 2x - 15x + 6 = 47

2. Combine like terms on the left side of the equation:

7 - 2x - 15x + 6 = 47 (7 + 6) - 2x - 15x = 47 13 - 17x = 47

3. Isolate the variable term (-17x) by moving the constants to the other side of the equation:

-17x = 47 - 13

-17x = 34

4. Finally, solve for x by dividing both sides by -17:

x = 34 / -17

x = -2

So, the solution to the equation is x = -2.
