Solution:
(See the solution in the photo)
Since this is in the Mathematics subject my best answer would be Rational.
Answer:
x = 5/3
Step-by-step explanation:
You ALWAYS want your term to be by itself!! So what you need to do is move your constant away from it.
Step 1: Adjust as needed, subtract 10 from both sides of your equation. It should end up like this.
-3x = 5 - 10
Step 2: Solve as needed before continuing equation.
-3x = -5
Step 3: Now you need to get your term by itself. You should divide -3 on both sides of your equation so you should get something like this.
x = -5 / -3
Step 4: You're basically done now! Just simplify! NEGATIVES CROSS EACH OTHER OUT!!!
x = 5/3 OR 1.6
<em>KEY:</em>
<em>Negative and Negative = Positive</em>
<em>Negative and Positive = Negative</em>
<em>Positive and Positive = Positive</em>
Answer:
p = -6.5
Step-by-step explanation:
-2(p-1) = 15
p-1 = -7.5
p = -6.5
Answer:
2/3=4/6 and that's 4 times 1/6. So the answer is 100% times 4 which is 400%
