2x-3y=-27, -3x+2y=23 what is the x-coordinate of the solution to the system?

Multiply 1st equation by 2 and 2nd by 3 add
4x - 6y = -54
-9x +:6y = 69
-5x = 15 divide both sides by -5
x = 3

Ithink the answer is a

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)
