Lerok [7]
For number 1.
Since AB + BC = AC
Then
-12x + 11 - 8x -4 = 127
-20x + 7 = 127
X = -6

Ab would then equal 83

One number is 3 less than twice another. If their sum is 39, find the numbers.
stiv31 [10]
Answer:
y = 2x- 3 and x + y = 39

Explanation:
Twice of a number indicates the 2x in the equation. It’s also 2 less than the 2x. That’s where the 2x-3 part comes from. The question indirectly states to find the sum of x and y. That sum should equal 39We can now plug in the information and get the second part of the equation, x+ y = 39
