4-1-D: Solve one-step addition and subtraction equations
{"Image DocumentName": "4-1-D: Solve one-step addition and subtraction equations", "Image ImageDescription": "Let\u2019s look at three more examples before we try it on our own. \ud835\udc66+6=9 \ud835\udc65+3=1 \u22123=\ud835\udc4e+4. \u22126=\u22126 \u22123=\u22123 \u22124= \u22124. \ud835\udc66 =3 \ud835\udc65 =\u22122 \u22127=\ud835\udc4e. Now you try! \ud835\udc4e+3=10. 9=\ud835\udc5f+2. \ud835\udc65+8=5. \ud835\udc66+15=11. If you are ever stuck and do not know what to do, ask yourself these three questions: What is my variable? What is being done to my variable? How can I UNDO what is being done to my variable? a = 7. r = 7. x = -3. y = -4.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
