Solve for m: 13 = 5m - 2

Back

m = 3

Front

Solve for a: a + 6 = 0

Back

a = -6

Front

Back

w = 2

Front

Solve for y: -2y = 20

Back

y = -10

Back

z = 7

Front

What is the first step to solve the equation 2x + 3 = 11?

Back

Subtract 3 from both sides to get 2x = 8.

Front

What is the second step to solve the equation 2x = 8?

Back

Divide both sides by 2 to get x = 4.

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means performing the same operation on both sides to maintain equality.
