15 + n = 24 (subtract 15 from both sides) n = 9
24 = 3x + 9 -9 -9 Subtract 9 from each side15 = 3x/3 /3 Divide 3 from each side5 = x You are left with five equals X
7P + 9 = 16 + 6P subtract 6P from BOTH sides P + 9 = 16 subtract 9 from both sides P = 7
24 + 9 = 33
24+-9=15
24
15 + n = 24 (subtract 15 from both sides) n = 9
Subtract 9 from both sides: 2x = 15, divide both sides by 2: x = 7.5
24 = 3x + 9 -9 -9 Subtract 9 from each side15 = 3x/3 /3 Divide 3 from each side5 = x You are left with five equals X
7P + 9 = 16 + 6P subtract 6P from BOTH sides P + 9 = 16 subtract 9 from both sides P = 7
You first multiply 6 by 13 giving you 78. Then subtract 9 giving you 69. Then subtract 6*6 which is 36 giving you 33. Then you subtract 9 to get 24.
24
To work out the answer to 3 plus 3 x 3 - 3 plus 3, you add 3 and 3 together which is 9, multiply 9 by 3 which is 27, subtract 3 which is 24 and add 3 to get the answer which is 27.
24 + 9 = 33
24+-9=15
You can only add or subtract like terms. So, you subtract 9x from 2x, which gives you -7x. Then subtract -9 from 3 to get -6. And you are left with -7x -6.
It is: (15-7)*(12-9) = 24
