What value of satisfies the equation 5a - 1 equals a -7?
5a - 1 = a - 7 4a = -6 a = -1.5
How do you solve the equation 5a plus 2 equals 7?
5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1
What is the solution of 6a plus 5a equals -11?
6a + 5a = -11 11a = -11 a = -11/11 = -1
What is the solution to 5a plus 11 plus 3a - 7 equals -4?
So we have 5a + 11 + 3a - 7 = -4 Start by combining common terms such as the 5a and 3a to give you 8a and 11 and -7 to give you 4. So now your equation is 8a + 4 = -4. Subtract 4 from both sides gives you 8a = -8. Divide -8 by 8 to give you a = -1, your solution.
Is x equals 1 a solution of the equation 2 - 8x?
No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a solution.
Solve the equation 2a plus 13 equals 5a 1?
If: 2a+13 = 5a+1 Then: a = 4
What value of satisfies the equation 5a - 1 equals a -7?
5a - 1 = a - 7 4a = -6 a = -1.5
What is an equation that has no solution called?
An equation that has no solution is called an equation that has no solution.
How do you solve the equation 5a plus 2 equals 7?
5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1
What is the solution of 6a plus 5a equals -11?
6a + 5a = -11 11a = -11 a = -11/11 = -1
What is the solution to 5a plus 11 plus 3a - 7 equals -4?
So we have 5a + 11 + 3a - 7 = -4 Start by combining common terms such as the 5a and 3a to give you 8a and 11 and -7 to give you 4. So now your equation is 8a + 4 = -4. Subtract 4 from both sides gives you 8a = -8. Divide -8 by 8 to give you a = -1, your solution.
Is 5a - 3 5(a 1) expression or equation?
It is an expression because it does not contain an equality sign.
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
If 5a 4a-1 equals 9a-4 what is the method used to get that answer?
Because of limitations with the question software, some symbols cannot be rendered, so we don't know what operation there is between the 5a and the 4a-1. Assuming a plus sign produces an inconsistent equation. But if we assume a / (slash) for division, we get a quadratic equation that produces some reasonable roots, so here's what I think the question is: Can you solve the following equation for a: 5a/(4a-1) = 9a-4 ? Yes you can! Multiply both sides of the equation by 4a-1. This gives you: 5a = (9a-4)(4a-1) Expand the right side, which gives you 5a = 36a2 -9a -16a + 4 Subtract 5a from both sides and group similar terms: 0 = 36a2 -30a + 4 Now, use the quadratic formula to solve for a(left to the student): a1 = 2/3; a2 = 1/6
An example of an equation and its solution?
1+1=2
Is x equals 1 a solution of the equation 2 - 8x?
No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a solution.
Does an equation has a solution?
Yes and sometimes it can have more than one solution.
