2(3x+4)> -2x+6 = -1 how to solve this equation

The answer would be -8, idk of the picture will show. hope this helped.

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.

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)
