3x equals 6x-15 then x plus 8 equals?
3x=6x-15 ....you want to take 6x and put it on the other side of the = sign. To do that you do the opposite. So you would subtract since 6x is a positive number. so then the equation is 3x-6x=-15. 3x-6x = -3x which makes the equation -3x=-15. Then you would take -3 which is being multiplied by x and do the opposite operation on the other side. so -3 divided by -15 equals 5. which makes the equation now x=5. So then 5+8=13
How do you solve 12x equals 24?
Well, isn't that just a happy little equation we have here! To solve for x, we can divide both sides by 12, which gives us x equals 2. And just like that, we've found the value of x that makes our equation balanced and complete. Keep up the good work, friend!
Does a solution to an equation make the equation true or false?
A solution to an question makes the equation true. For example a solution to the equation 3x = x + 6 is x = 3, since 3(3) = 3+6.
Which equation is satisfied by all three of the plotted points in order from x to y -4 -3 0 -1 4 1?
This question makes no sense! Which are the x-values, and which are the y-values?
Choose the ordered pair that is a solution to the system of equations -x plus y equals 12?
-x+y=12is the equation of a line and since there are infinitely many points on the line and each point is represented by an ordered pair, we have infinitely many solutions.If we take x as 0, then y must be 12so (0,12) is one ordered pair that is a solution to the equation.Zero is often a nice number to pick since it makes the calculation a bit easier.
