Twice the sum of a number and 3 is the same as 5 subtracted from the number. find the number.

1 answer:

3 0

Translating this sentence into symbols: 2(x+3) = x - 5

So 2x + 6 = x - 5 and x = -11

Check: Is 2(-11+3) = -11 -5? Is -16 = -16? YES. x =-11 is right.

J, (8,-3) because since they are diagonals, you can take the x and y values between the vertices and point of intersection.

For x
The distance between 2 and -4 is 6. Moving 6 in the other direction results in an x value of 8 (2+6)

For y
The distance between 5 and 1 is 4. Moving 4 in the other direction gives you a y value of -3 (1-4)

The answer is therefore (8,-3)
