-15 + 4 = -11
I think x equals 2 or 4. I'm not really sure. It probably equals two, though.
23 + 4 = 27
In math problems without punctuation such as brackets, the standard convention in to solve from left to right. Therefore, you would solve the problem 15-3 times 4 plus nine like by three actions. 15-3 equals 12; 12 times 4 equals 48; 48 plus 9 equals 57.
27
That equals 28
2 squared is 4 3 cubed is 27 27 plus 4 is 31
75 / 15 + 4 + 7 = 16
x=4
Yes. The answer is......................................................................................................................................................................................................................................................2.
