(x^2 - 3x + 1) - (x^2 + 2x + 7)
Distribute the negative
x^2 - 3x + 1 - x^2 - 2x - 7
Combine like terms
-5x - 6
Answer:
the answer is 0.9988747935
hope that works!!
4a-8=28
add 8 to both sides to start to isolate the variable (a)
-8+8 cancels each other out
28+8=36
4a=36
to completely isolate the variable divide both sides by 4
4a÷4=a
36÷4=9
a=9
Answer:
n+8 = 40
n=32
Step-by-step explanation:
Let the number be n
8 more than means
n+8
is equal to
n+8 =
n+8 = 40
We can solve this by subtracting 8 from each side
n+8-8=40-8
n = 32
The number is 32
