a+3-1x3+2-4+0x1=0
a+3-3+2-4+0=0 a-2=0 a=2
ust use your order of operations... PEMDAS. Parenthesis, exponents, multiplication, division, addition, subtraction. MD and AS can occur in any order, left to right. a + 3 - 1 * 3 + 2 - 4 + 0 * 1 = 0 I'll add parenthesis to show the order of operations. a + 3 - (1 * 3) + 2 - 4 + (0*1) = 0 a + 3 - 3 + 2 - 4 + 0 = 0 So let's get the variable by itself. a + 3 - 3 + 2 - 4 = 0 a + 3 - 3 + 2 = 4 a + 3 - 3 = 2 a + 3 = 5 a = 2 So there we go. I overcomplicated it on purpose, but a = 2.
