What is the answer to 4a-3 equals 2a plus 7?
a=5
4a - 5b equals 7 4a plus 5b equals 17?
4a - 5b = 74a +5b = 17From the first equation:4a = 7 + 5bsubstitute this value in the second equation:7 + 5b + 5b = 177 + 10b = 1710b = 10b = 1Now,solve for a :4a - 5(1) = 74a = 7 + 54a = 12a = 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 plus 35 divided by -7 simplified?
(7a + 35)/-7 = 7(a + 5)/-7 = -(a + 5) = (-a - 5)
How do you simplify a2 plus 7a-8a2 equals 6a7?
a2 + 7a - 8a2 = 6a7 ∴ a2 + 7a - 8a2- 6a7 = 0 ∴ a + 7 - 8a - 6a6 = 0 ∴ 7 - 7a - 6a6 = 0 ∴ 6a6 + 7a - 7 = 0
Evaluate a+4a+4a, plus, 4 when a=7a=7a, equals, 7?

7a2 plus 53a plus 28 equals?
7a2 + 53a + 28 = 7a2 + 49a + 4a + 28 = 7a(a + 7) +4(a + 7) = (a + 7)(7a + 4)
What is the answer to11a plus 9 equals 4a plus 30?
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

How do you simplify a over 7 and a over 4?
a/7 + a/4 = 4a/28 + 7a/28 = 11a/28
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 plus 35 divided by -7 simplified?
(7a + 35)/-7 = 7(a + 5)/-7 = -(a + 5) = (-a - 5)
Solve a over 5 plus a over 2 equals 14 over 2?
a/5 + a/2 = 14/2 2a/10 + 5a/10 = 7 7a/10 = 7 7a = 70 a = 10
7a plus 4 equals 5a plus 7?
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
How do you simplify a2 plus 7a-8a2 equals 6a7?
a2 + 7a - 8a2 = 6a7 ∴ a2 + 7a - 8a2- 6a7 = 0 ∴ a + 7 - 8a - 6a6 = 0 ∴ 7 - 7a - 6a6 = 0 ∴ 6a6 + 7a - 7 = 0
