If you have the equation x + a = b, how do you solve for x?

• Add a to both sides: x = b + a.

• Multiply both sides by a: x = b * a.

• Subtract a from both sides: x = b - a.

• Divide both sides by a: x = b / a.

What is the purpose of solving equations?

• To find the value of the variable that makes the equation true.

• To simplify the equation without finding any values.

• To create new equations from existing ones.

• To determine the number of solutions an equation can have.

What does it mean to isolate a variable in an equation?

• To manipulate the equation so that the variable is on one side and all other terms are on the other side.

• To eliminate the variable from the equation entirely.

• To replace the variable with a constant value.

• To combine like terms on both sides of the equation.

Solve for x: x + 13 = 25

• x = 10

• x = 11

• x = 12
