Step-by-step explanation:
Answer: (x-1)(3x+8)
Step-by-step explanation:
Slide and divide method
See what multiplies to get -24 (because of 3 and -8) and what adds to get 5
Put those into factoring form (x-3)(x+8) without a number in front of the x’s
Divide the numbers by what isn’t in front of the x’s (-3/3 and 8/3)
Simplify them and if it doesn’t divide perfectly, put the denominator in front of the x
Solution
**I can’t explain it well but watch a video on the method AND ONLY DO IT IF IT WORKS WELL FOR YOU**
Answer:

Simple...
you have: -7=c-6
You want to isolate the variable c
-7=c-6
-7=c-6
+6 +6
-1=c
Thus, your answer.
Answer:
Step-by-step explanation:
2 1/2 + x = 5 1/3 Change the mixed numbers to improper fractions
5/2 + x = 16/3 The lowest common multiple is 6. Multiply by 6
5*3 + 6x = 16*2
15 + 6x = 32 Subtract 15 from both sides.
6x = 32 - 15
6x = 17 Divide by 6
6x/6 = 17/6
x = 2 5/6
Check
5/2 + 17/6 = 16/3
15/6 + 17/6 = 32/6
32/6 = 32/6 The question checks.
