First, you need to get rid of the fraction by multiplying both sides by 20 and you would get:
4(x + 2) = 5(x + 6)
Now, you need to get rid of the parenthesis by distributing:
4x + 8 = 5x + 30
Subtract both sides by 5x:
-x + 8 = 30
Subtract both sides by 8:
-x = 22
Now, divide both sides by -1:
x = -22
P.S.: You don't really need a calculator to solve.
Answer:
9
Step-by-step explanation:
Whatever you do to the denominator, you've got to do to the numerator, and vice versa. So for 8 to become 24, you multiply by 3. do that to the numerator 3 as well. 3 × 3 is 9.
4•(-9)•(-3)•(-1) is negative. Here's how:
4•(-9)•(-3)•(-1)
(-36)•(3) = -108
-2•(-7)•12•(4)
14•48 = 672
-6•(-7)•(-8)•0
42•(0) = 0
-3•(-2)•(-4)•(-7)
6•28 = 168
I can help, just ask the question a little better
