Simplify 2a plus 3a plus 4 equals?
2a + 3a + 4 = 5a + 4
7a2 plus 53a plus 28 equals?
7a2 + 53a + 28 = 7a2 + 49a + 4a + 28 = 7a(a + 7) +4(a + 7) = (a + 7)(7a + 4)
Solve each equation 2a-4 459-a check?
2a-8+4=45-5a 2a-4=45-5a 2a-4+4=45+4-5a 2a+5a=49-5a+5a 7a=49 / by 7 = A=7
Describe a symbolic method for solving a linear equation?
i dont understand what you mean by symbolic but ill just do an example 2a + 3 = 4 - 5a first collect like terms 2a +3 -3 = 4 -3 -5a 2a = 4-3 - 5a 2a + 5a = 1 - 5a + 5a 2a + 5a = 1 7a = 1 divide both sides by the coefficient of the unknwown(i.e. the number in front of the letter) 7a/7 = 1/7 a = 1/7
What is the answer to -5a equals 20?
a= -4 because a negative times a negative equals a positive
What is five times the sum of some number plus 3 is equal to 7 times the number minus 1?
5a + 3 = 7a - 1 add 1 to both sides 5a + 4 = 7a so 4 = 2a as 5a + 2a = 7a 4 = 2a = 2 x 2 so a = 2 Check: then 5a + 3 = 10 + 3 = 13 and 7a - 1 = 14 - 1 = 13
Evaluate a+4a+4a, plus, 4 when a=7a=7a, equals, 7?

What is the answer to 12 plus 5a squared if a equals 4?
92
What is the answer for 3a plus 13 equals 5a plus 5?
a is equal to 4
How do you solve 6a plus 4 equals 5a-2?
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
Simplify 2a plus 3a plus 4 equals?
2a + 3a + 4 = 5a + 4
Solve the equation 2a plus 13 equals 5a 1?
If: 2a+13 = 5a+1 Then: a = 4
7a2 plus 53a plus 28 equals?
7a2 + 53a + 28 = 7a2 + 49a + 4a + 28 = 7a(a + 7) +4(a + 7) = (a + 7)(7a + 4)
If a equals -5 and b equals 4 what would 5a plus 3b equal?
-13
Solve each equation 2a-4 459-a check?
2a-8+4=45-5a 2a-4=45-5a 2a-4+4=45+4-5a 2a+5a=49-5a+5a 7a=49 / by 7 = A=7
5a plus d - bc equals a equals 5 b equals 7 c equals 2 d equals 4 what is the correct answer?
4
How do you do 7a plus 8 equals 6a plus 14?
A = 4 (7x4) + 8 = 36 (6x4) + 14 = 36
