Thursday- Two step equations Finish for HW

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform the inverse operations in reverse order: first undo addition or subtraction, then undo multiplication or division.

Front

Solve for n: 3n + 4 = 7

Back

n = 1

Front

Solve for m: -5 = 3m - 14

Back

m = 3

Front

Solve for s: 9 = 2s + 1

Back

s = 4

Front

What is the first step to solve the equation 3n + 4 = 7?

Back

Subtract 4 from both sides to get 3n = 3.

Front

What is the second step to solve the equation 3n = 3?

Back

Divide both sides by 3 to find n = 1.

Front

Solve for a: a + 4 = -2

Back

a = -6

Front

Solve for a: a - 3 = -5

Back

a = -2

Front

What does it mean to 'solve for a' in an equation?

Back

To 'solve for a' means to find the value of the variable 'a' that makes the equation true.
