Solve the equation x + 10 = 30 and describe your steps.

what are inverse operations? describe the inverse operations for addition, subtraction, multiplication and division.

how do you move a variable from one side of the equal sign to the other?

solve and describe the steps used to find x for the equation 2(x + 4) – 10 = 12

what does it mean for an equation to have no solution or infinite solutions? how does the equation appear when those are the outcomes.

1) x+10=30
-10 -10
x = 20

2) I don't remeber

3) depending on if it is positive or negative you would subtract of positive or add if the variable is negative the move it to the other side ex:
2x +45 = -x + 10
+x +x =
3x + 45 = 10

4) 2(x+4) - 10 = 12
first minus the 10
2 (x+4) = 2
then multiply the 2
2x + 8 = 2
then subtract the 8
2x = -6
divide both sides by 2 so that x is alone that's ur main goal
x= -3

5) no solution means after you did a check and it doesn't work, and there's noistake it means it's a no solution. infinite solution means it has more than one answer
