Match the equation with the step needed to solve it.
ziro4ka [17]

To solve this, you need to isolate/get the variable "m" by itself in the equation:

1. 2m - 1 = 3m    Subtract 2m on both sides to get "m" on one side of the equation

2m - 2m - 1 = 3m - 2m

-1 = m

2. 2m = 1 + m     Subtract m on both sides to get "m" on one side of the equation

2m - m = 1 + m - m

m = 1

3. m - 1 = 2       Add 1 on both sides to get "m" by itself

m - 1 + 1 = 2 + 1

m = 3

4. 2 + m = 3   Subtract 2 on both sides to get "m" by itself

m = 1

5. -2 + m = 1      Add 2 on both sides to get "m" by itself

m = 3

6. 3 = 1 + m     Subtract 1 on both sides to get "m" by itself

2 = m

Solve 3x to the <br> second power <br> -2x-8=0 using an algebraic method
MatroZZZ [7]

Answer:

x=2\textrm{ or } x=-\frac{4}{3}

Step-by-step explanation:

Given:

The equation is given as:

3x^{2}-2x-8=0\\3x^{2}-6x+4x-8=0\\3x(x-2)+4(x-2)=0\\(x-2)(3x+4)=0\\\\x-2=0\textrm{ or }3x+4=0\\x-2+2=0+2 \textrm{ or }3x+4-4=0-4\\x=2\textrm{ or }3x=-4\\x=2\textrm{ or}\\x=-\frac{4}{3}

Therefore, the possible values of x are 2 and -\frac{4}{3}
