Some problems compared: literal vs one variable

1. SOLVING EQUATIONS One step, more steps and those with more than one variable!!

2. Solve for a variable. Solve for x = Solve for x = 2x + 5 = 10 Given problem 2x = 5 Subtraction Prop X = 5/2 Division Prop Ax + z = P Given problem Ax = P – z Subtraction pr X = (P – z) /A Division Prop

3. Solve for y = mx + b This procedure will be very important in the upcoming modules! Given: 2x + 3y = 12 Solve for y = 3y = -2x +12 Y = -2x/3 + 4 Given: 3x – 2y = -10 Solve for y = -2y = -10 -3x Y = 5 + 3x/2
