18,560 - 15,787 = 2,773
2773/18560 x 100 = 14.94 which is rounded up to about 15%
There can only be one reason for that . . . making
something tough out of something easy.
<u>-19 = x - 7</u>
How could you get 'x' all by itself on one side,
and everything else on the other side ?
What if you add 7 to each side ?
Then you have <em> -12 = x </em> . To your amazement, that's the solution !
3X - 4Y = 9
-3X + 2Y = 9
first step is try to get rid of one of the variables and solve for the other one. In this example you dont need to manipulate the equations to get one variable to cancel.
the x term cancels out. add both equations
-2y = 18
y= - 9
now we plug the y term back into an original equation and solve for x
3x - 4(-9)=9
3x=-27
x=-9
hope that helps
I solved it this way , hope it’s correct ;)
