2x-3+12= 6 move the +12 over to become -12
2x-3=(6-12= -6) then move -3 over so it becomes +3
2x=(-6+3= -3) then take the two over so you divide by two
x=(-3 divided by 2= -1.5) so x = -1.5

32 divided by 4 equals 8 plus 4 equals 12 multipled by 8 equals 96 answer
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
6+8=14
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.
10n+12 = 14n-12 10n-14 = -12-12 -4n = -24 n = 6
