-3(10-х)=-10х-4

To solve this equation, we need to distribute the -3 on the left side of the equation:

-3(10 - x) = -10x - 4 -30 + 3x = -10x - 4

Now, let's simplify the equation by combining like terms:

3x + 10x = 30 - 4 13x = 26

Divide by 13 to solve for x:

x = 26 / 13 x = 2

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