open response
4+8(3x-2)-7x=17x-12 how did i get the answer 8*3x=24x 8*2=16 4+24x-16-7x=17x-12
To solve the equation 4+8(3x-2)-7x=17x-12, you can follow these steps:
1. Distribute the 8 to terms inside the parentheses:
4 + 8(3x) - 8(2) - 7x = 17x - 12
2. Simplify:
4 + 24x - 16 - 7x = 17x - 12
3. Combine like terms on both sides of the equation:
(24x - 7x) + (4 - 16) = 17x - 12
17x - 12 = 17x - 12
4. Notice that we have 17x on both sides of the equation. This means that the two sides are equal, and any value of x will make the equation true.
Therefore, the solution to the given equation is any real number x.
