Answer: z = −36
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
-12 = 1/3z
Step 2: Flip the equation.
1/3x = -12
Step 3: Multiply both sides by 3.
3* (1/3z) = (3) * (-12)
Answer:
x = 1.56
Step-by-step explanation:
so what you have to do is isolate the variable by dividing each side by factors that don't contain the variable.
I hope this helped and have a great day.
You need to times 2/3 twice
-2/-3 * -2/3
Simplifying
12x + 10 + 3 + 8x = 0
Reorder the terms:
10 + 3 + 12x + 8x = 0
Combine like terms: 10 + 3 = 13
13 + 12x + 8x = 0
Combine like terms: 12x + 8x = 20x
13 + 20x = 0
Solving
13 + 20x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 20x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 20x = 0 + -13
20x = 0 + -13
Combine like terms: 0 + -13 = -13
20x = -13
Divide each side by '20'.
x = -0.65
Simplifying
x = -0.65
B is the answer to the question.
