Your subject is NOT college.
3(4x-7)=10x
12x - 21 = 10x
2x = 21
x = ?
-12x + 21 = 10 x
21 = 22 x
x = 21/22
To solve the given equation, -3(4x-7) = 10x, we need to simplify both sides of the equation and then isolate the variable x.
Let's start by simplifying the left side of the equation using the distributive property:
-3 * 4x - 3 * (-7) = 10x
Simplifying further:
-12x + 21 = 10x
Now, let's isolate the x terms on one side of the equation. We can do this by moving the variable terms to one side and the constant terms to the other side:
-12x - 10x = -21
Combining like terms:
-22x = -21
To solve for x, we divide both sides of the equation by -22:
x = -21 / -22
Simplifying further, the negative signs cancel each other out:
x = 21 / 22
Therefore, the solution to the equation -3(4x-7) = 10x is x = 21/22.
