What is the first step to solve the equation $$5x - 3 = 12$$ ?

The first step is to add 3 to both sides of the equation, resulting in $$5x = 15$$ .

What is the solution to the equation $$3x + 4 = 19$$ ?

Subtract 4 from both sides to get $$3x = 15$$ , then divide by 3 to find $$x = 5$$ .

Solve for x: $$x - 7 = 3$$

Add 7 to both sides to get $$x = 10$$ .

What is the definition of an equation?

An equation is a mathematical statement that asserts the equality of two expressions, typically containing one or more variables.

How do you solve the equation $$-10 = \frac{x}{6} - 12$$ ?

Add 12 to both sides to get $$2 = \frac{x}{6}$$ , then multiply both sides by 6 to find $$x = 12$$ .

What is the solution to the equation $$-6w + 1 = -11$$ ?

Subtract 1 from both sides to get $$-6w = -12$$ , then divide by -6 to find $$w = 2$$ .

What is the definition of a coefficient in algebra?

A coefficient is a numerical factor that multiplies a variable in an algebraic expression, such as the 3 in $$3x$$ .

Solve for x: $$5x + 7 = -13$$

Subtract 7 from both sides to get $$5x = -20$$ , then divide by 5 to find $$x = -4$$ .

What is the purpose of using inverse operations in solving equations?

Inverse operations are used to undo operations in order to isolate the variable and solve the equation.

What is the definition of a constant in algebra?

A constant is a fixed value that does not change, such as the number 5 in the expression $$x + 5$$ .
