Standard 6.EE.7
Solve real-world and mathematical problems by writing and solving equations of the
form x + a = b and ax = b for cases in which a, b and x are all non-negative rational
numbers.
Solving for x: x + B = C
Get x alone on one side of the equal sign
To do this, eliminate the constant on the same side as x by using the inverse operation to cancel it out
REMEMBER! What you do on one side, must be done on the other side to keep the equation proportional
x + B - B = C - B ------> x = C - B
X - B + B = C + B—---.> x = C + B

Solving for x: Ax + B = C
Ax + B - B = C - B ------> Ax = C - B
Ax / A = (C - B) / A -----> x = (C - B) / A
