Answer:
Step-by-step explanation:
<u>2x + 3x</u> - 10 = 90
Combine like terms
5x - 10 = 90
Add 10 to both sides
5x = 90+10
5x = 100
Divide both sides by 5
x =100/5
x = 20
Answer:
i think it is E
Step-by-step explanation:
Answer: -28 degrees Celsius
Step-by-step explanation:
-20 - 8 = -28
Answer:
−2(−9x+5)−4x=2(x−5)−4
Step 1: Simplify both sides of the equation.
−2(−9x+5)−4x=2(x−5)−4
(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)
18x+−10+−4x=2x+−10+−4
(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)
14x+−10=2x+−14
14x−10=2x−14
Step 2: Subtract 2x from both sides.
14x−10−2x=2x−14−2x
12x−10=−14
Step 3: Add 10 to both sides.
12x−10+10=−14+10
12x=−4
Step 4: Divide both sides by 12.
12x
12
=
−4
12
x= -1/3
