7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6
How do you evaluate expression 0.2 x n for n equals 3 and n equals 6?
3 6
How do you evaluate D equals 35 times 6?
D = 210
7a plus 4 equals 5a plus 7?
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
How do you solve 7a-b equals 15a and solve for a?
-8
Evaluate a+4a+4a, plus, 4 when a=7a=7a, equals, 7?

What is 7a plus 6 equals -36?
7a + 6 = -36 Subtract 6 from both sides: 7a = -42 Divide both sides by 7: a = -6 a = -6
What is the answer to A plus 18 equals 7a?
a + 18 = 7a a-a +18 = 7a-a 18 = 6a 18/6 = 6a/6 3 = a 3=a
What is the variable for 8a-9 equals 7a-6?
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3
How do you solve 4a-2 equals 7a-6?
4a-2=7a-6 4=3a a=4/3
Evaluate 3 a plus 4 a 6?
3a + 4a +/- 6; take the 3a & 4a and combine them; 7a +/- 6 would be your answer as 6 cannot combine with 7a due to the variable. If 7a +/- 6 = 0, then subtract/add (respectively) the 6 depending on the operation. Therefore 7a + 6 = 0 turns to 7a = -6. Divide the 7 with the -6 to get the a alone; a = -6/7 or -0.8. Cannot be simplified.
7a-17 equals 4a plus 1?
7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6
Evaluate a-2 for a equals 8?
6
What is 7a-a-a-a equals?
4a
Solve the equation 9a-a equals 19 plus 7a?
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
9a plus 15 equals 7a plus 9?
Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3
