11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3
9 x 27 equals 243
5/9=x/27 135=9x 15=x
To solve this we simply plug in the value of x where any x's are found in the equation. 1) 27x - 27; x = -9 2) 27(-9) - 27 3) -243 - 27 = -270 So, 27x - 27 = -270 if x = -9.
27 divided by 3 equals 9. 27 divided by 9 equals 3.
9=4a+13 9-13=4a -4=4a -4/4=a -1=a a=-1
11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3
9 x 27 equals 243
2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14
4a+3-a =12 4a-a = 12-3 3a = 9 a = 3
-1
5/9=x/27 135=9x 15=x
3/9 = x/81 x = 27 So: 3/9 = 27/81
11a + 9 = 4a + 30Subtract 9 from both sides to get: 11a = 4a + 21Subtract 4a from both sides to get:7a = 21Divide both sides by 7 to get:a = 3And there's your answer: a = 3
To solve this we simply plug in the value of x where any x's are found in the equation. 1) 27x - 27; x = -9 2) 27(-9) - 27 3) -243 - 27 = -270 So, 27x - 27 = -270 if x = -9.
3m + 9 = 36subtract 9 from both sides3m = 27divide both sides by 3m = 27/3 = 9
27 divided by 3 equals 9. 27 divided by 9 equals 3.
