step 1: x - 9 = -30
step 2: x = -30 + 9
step 3: x = -21
x+6/2 = 9/5 Start x+3 = 9/5 Simplify 6/2 into 3 x + 3 = 1.8 Simplify 9/5 into 1.8 x = 1.2 Subtract 1.8 from 3 (or x = 6/5)
Order of operations. Do subtraction last. 6 x 5 x 9 x 1 x 5=1350. 7-1350=-1343
3/5
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
x-9 = 5 x = 5+9 x = 14
(6 x 4) + (6 x 5) + (6 x 6) + (6 x 7) + (6 x 8) + (6 x 9) = 234
6
Do the multiplication first, giving 5 + 6 + 6 + 9, ie 26
10-6+5 = 9
-6
6 * 5 = 30
x=9
