Obviously, a=3 To show... Simultaneously subtract the smaller variable on the right side (7a) from both sides and the lesser constant on the left side (-9) from both sides (subtracting a negative means to add a positive), or in other words... Subtract 7a from and add 9 to both sides to instantly force the value of 'a'... (1)a = 3 There, you have your answer... a=3

9a plus 15 equals 7a plus 9?
Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3
What is the answer to 11a plus 9 minus 3A equals -7?
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
2a plus 21 equals 8a-9?
2a + 21 = 8a - 9Add 9 to each side:2a + 30 = 8aSubtract 2a from each side:30 = 6aDivide each side by 6:5 = a
A plus 6A minus 9 equals 30?
a + 6a - 9 = 30 7a - 9 = 30 7a = 30 + 9 7a = 39 a = 39/7 a = 5.571 (to 3 decimal places only).
What is the answer for -7a plus 2a plus 9 equals 24?
