Front

What does it mean when an equation has many solutions?

Back

It means that there are infinitely many values for the variable that satisfy the equation.

Front

Simplify the expression: 5x + 12 - 16w - 16 + 18w - 6x

Back

2w - x - 4

Front

What is the first step to solve the equation: 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the solution to the equation: 7x - 3x - 8 = 24?

Back

x = 8.

Front

How do you find the y-intercept of the equation y = -x + 2?

Back

Set x = 0 and solve for y. The y-intercept is (0, 2).

Front

What does it mean if an equation has no solution?

Back

It means that there are no values for the variable that can satisfy the equation.

Front

What is the process of combining like terms in an expression?

Back

It involves adding or subtracting coefficients of the same variable.

Front

What is the first step in solving the equation: 3(x - 2) = 12?

Back

Distribute 3 to both terms inside the parentheses.

Front

What is the definition of a variable in algebra?

Back

A symbol, usually a letter, that represents an unknown value.
