How many solutions does the equation have? 4(x-3)=4x-12

There are infinitely many solutions

4(x - 3) = 4x - 12
4x - 12 = 4x - 12
     + 12       + 12
4x = 4x
-4x   -4x
0 = 0

When your answer is equal on both sides, that means that there are infinite solutions. In other words, they are the same line. This means that they share all of the same points, which are infinite.

Hope this helps!

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
