If x is "the number," which of the following equations could be used to solve for the number?
3x + 4 = 28
3 x= 4 + 28
3( x + 4) = 28

3x+4=28 because 3 times an unknown number was mentioned first and mentioned together so they will be together, increased by 4 is +4 and comes after, the result of is the same as equals so you put the equals sign and whatever number they gave after.
