Answer:
The answer would be -4x - 42.
Step-by-step explanation:
Goal: Simplify the equation.
- You need to distribute the - sign where it isn't. So the equation should look like this now: 4(-3-5)+-1(10+4x).
- Now multiply -1(0+4x): (-1)(10) + -1(4x) to get 4(-3-5) +-10+-4x
- Now multiply 4(-3-5): (4)(-3)= -12 / (4)(5) = 20 / -12-20 = -32
- The equation should now look like: -32 + -10 + -4x
- Next, we need to combine like terms and since the like terms are -32 and -10, the equation should look like: -4x + (-32 + -10).
- Add -32 with -10: -32 + -10 = -42.
- You can't do anything with the -4x so therefore, the equation would be -4x - 42.

Answer:
y = 2
Step-by-step explanation:
Given
y + 7 = 9 ( subtract 7 from both sides )
y = 2
Answer:
this depends on the grading system, but if everything is equal and you made a 0, then it will be around a 50
Answer:
x = 4/(k + 3)
Step-by-step explanation:
kx+3x=4
Take out a common factor between 3x and kx.
X(k + 3) = 4
Now divide by k +3
x = 4/(k + 3)
