To find 40% of 68
you simply divide 40% by 100 and multiply by 68
40/100 x 68 = 32.64
32.64 is 40% of 68.
The same steps can be used to find any percentage of any number.
simply divide the percentage given by 100 and multiply by the total number.
Equation 1: y = -2x + 1
Equation 2: y = 2x - 3
Since both equations already have y isolated, we are able to simply set the right side of both equations equal to each other. Since we know that the value of y must be the same, we can do this.
-2x + 1 = 2x - 3
1 = 4x - 3
4 = 4x
x = 1
Then, we need to plug our value of x back into either of the original two equations and solve for y. I will be plugging x back into equation 2 above.
y = 2x - 3
y = 2(1) - 3
y = 2 - 3
y = -1
Hope this helps!! :)
