To solve 10x-35+3ax=5ax-7a, we'll need to assume that a is a constant and that we are to solve for the variable x. To accomplish this, group all the x terms together on one side and all of the no-x terms on the other:
10x + 3ax - 5ax = -7a + 35
Factoring x out of the left side, we get:
x(10 - 2a) = 7(5 - a). Dividing both sides by (10 - 2a), we get:
7(5 - a)
x = ------------ = 7/2
2(5 - a)
x has the value 7/2.
![x=-2 \\ y=-3](https://tex.z-dn.net/?f=x%3D-2%20%5C%5C%20y%3D-3)
The equation
![3x\leq2y](https://tex.z-dn.net/?f=3x%5Cleq2y)
can now be rewritten:
![3\times(-2)\leq2\times(-3)](https://tex.z-dn.net/?f=3%5Ctimes%28-2%29%5Cleq2%5Ctimes%28-3%29)
And simplified.
![-6\leq-6](https://tex.z-dn.net/?f=-6%5Cleq-6)
Which means the statement is true because operation states less than or equal to.
Direct answer: True
The answer is: " - 49 " .
_____________________________
The problem: "What is "-7" multiplied by "the absolute value of (7)"?
Note: The absolute values of (7) = 7 ; that is the absolute values of (positive 7) is: "(positive 7)" .
__________________________
So, we are left with: What is: "-7 " multiplied by "+ 7" ;
{i.e. , " (-7)*(7) = ? " } ;
_________________________
The answer is: " -49 " .
