your expression is this...
n+5=3+12
n+5=15
n=10
12 divided by 4 plus 2 times 3 = 9
If: -3a+2 = 12 Then: a = -3 and 1/3
36
12-3(2+15) = -39
12
9 divided by 9 equals 1, and 3 times 12 equals 36. 1 plus 36 equals 37.
3*-5+27 equals 12.
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.
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
