In the equation, 5x + 12= -2x - 7 +12 , what is one of the steps that should be taken to solve for x?
a Combine like terms.
b Subtract 7 from both sides of the equation.
c Divide both sides of the equation by 3.
d Divide both sides of the equation by 5.

a.) Combine like terms.

Step-by-step explanation:

When solving equations that involve unknown variables, there are many steps to take to help one solve for the unknown variable. These steps include,

1.) combining like terms so that you can have similar terms on one side of the equation.

2.) Subtracting or adding A term that may be common to both side of the equation so you can be left with simpler terms to deal with

3.) diving or multiplying by a common factor to both sides of the equation so you can have a simpler equation to deal with.

Going by the above conditions and checking With the available options, combining like terms is the feasible step to take among the given options.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
