Step-by-step explanation: Simplifying
3x2 + 48 = 0
Reorder the terms:
48 + 3x2 = 0
Solving
48 + 3x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-48' to each side of the equation.
48 + -48 + 3x2 = 0 + -48
Combine like terms: 48 + -48 = 0
0 + 3x2 = 0 + -48
3x2 = 0 + -48
Combine like terms: 0 + -48 = -48
3x2 = -48
Divide each side by '3'.
x2 = -16
Simplifying
x2 = -16
Reorder the terms:
16 + x2 = -16 + 16
Combine like terms: -16 + 16 = 0
16 + x2 = 0
The solution to this equation could not be determined.
Answer:
x<10
Step-by-step explanation:
Add '-7' to each side of the equation.
7 + -7 + -0.3x = 4 + -7
Combine like terms: 7 + -7 = 0
0 + -0.3x = 4 + -7
-0.3x = 4 + -7
Combine like terms: 4 + -7 = -3
-0.3x = -3
Divide each side by '-0.3'.
x = 10
Simplifying
x = 10
