Answer:
-42
Step-by-step explanation:
-2y = 46
y = 46/ -2
y = -23
Substitute y in y = 4x-11
-23 = 4x -11
-23+11 =4x
-12 = 4x
x = -12/4
x = -3
Now plug in x value in 14x
14(-3) = -42
Difference means subtract so we can reduce the choices right away to first and third choices. of the only the first is the difference of squares, namely x² - 4²
Answer:
28
Step-by-step explanation:
18+6+4=28
1.Identify the fractions. Using the distributive property, you’ll eventually turn them into integers.
2.For all fractions, find the lowest common multiple (LCM) -- the smallest number that both denominators can fit neatly into. This will allow you to add fractions.
3.Multiply every term in the equation by the LCM.
4.Isolate variables adding or subtracting like terms on both sides of the equals sign.
5.Combine like terms.
6.Solve the equation and simplify, if needed.
