Solving equations
Download as PPTX, PDF0 likes206 views
This document discusses how to solve different types of equations: equations with one variable, more than one variable, and equations that can be written in the form of y = mx + b. It provides examples of solving equations with one variable by using the subtraction and division properties, and examples of solving equations for y in terms of x by isolating y and using the division property. Mastering these techniques is important for upcoming modules dealing with more advanced equation solving.

Solving equations
- 1. SOLVING EQUATIONSOne 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 problem2x = 5 Subtraction PropX = 5/2 Division PropAx + z = P Given problemAx = P – z Subtraction prX = (P – z) /A Division Prop
- 3. Solve for y = mx + bThis procedure will be very important in the upcoming modules!Given: 2x + 3y = 12 Solve for y =3y = -2x +12Y = -2x/3 + 4 Given: 3x – 2y = -10 Solve for y =-2y = -10 -3xY = 5 + 3x/2
