| 4y-13 = 35
-13 -13 |
1) You must begin by adding 13 to both sides of the equation.The 13 cancels out on the left side of the equation. |
| 4y = 48
/4 /4 |
2) Next you must divide both sides by 4. |
| x = 12 | 3) The answer is .................. x=12. |
| A = (b1+b2) H
` 2 |
|
| 2A = (b1+b2)h
H h |
1) You must begin by doing the opposite of multiply and divide both sides of the equation by H. |
| 2A =b1 +b2
A |
2) Next you subtract b2 from both sides. |
| 2A - b2 =b1
h |
3) This is your answer. |
| 3x+b=y (2,8) | |
| 3 (2) +b =8
|
1) First you distribute the coodinates |
| 6+b =8
-6 -6 |
2) Next you subtract -6 from both sides. |
| b =2 | 3) your answer is b =2. |
