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.

3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15

The link below will help you.
5/3 - 4/5 = 25/15 - 12/15 = 13/15
x = 3*0.4 = 1.2
subtract 15 from both sides then divide both sides by -4. g=12
80 = 3y + 2y + 4 + 1 75 = 5y 15 = y y = 15
(25/100) x 15 = 3.75 or 15 x 0.25 = 3.75 or 15 x 1/4 = 3.75

Ill show you some examples: Ex. 1:3x + 4 - x + 16 + 12x(4 + 16) + 3x - x +12x20 + 2x + 12x20 + 14xEx. 2:15 - 12x + 4 - 2 + 6x(15+4-2) - 12x + 6x(19-2) - 12x + 6x17 - 18xTo solve these problems, first group like numbers. Then solve the problem until you can't solve anymore!
4b + 3 = 15 First, Subtract 3 from both sides. -3 -3 4b = 12 Then, divide by 4 to get b by itself. 4 4 b = 3
