| Question | Answer |
| 5x+4=24 | How to work it Subtract 4 on both sides. -4-4=0 (they cancel each other out) 24-4=20 5x=20 Divide both sides by 5. 5 divided by 5 is 1, and 5 divided by 20 is 4. So x=4 |
| -3.2x + 4.8 =10.6 | How to work it Subtract 4.84 on both sides 4.84-4.84=0 10.6-4.84=5.76 So your left with -3.2x and 5.76. Divide both of them by -3.2. x=-1.8x |
| a+5 ----------------- = 12 3 (the lines under a+5 is a fraction bar) | How to work it (A easy way to do it ) Since the denominator is 3 we multiply that and the answer by 3. (shown below) a+5 3-------- = 12 x 3 3 We cross the two 3's out and multiply 12 times 3. So now it's a regular equation. a+5=36 Subtract 5 from both sides a=31 |
| The equation is 2x over 5 + 3 - 4x over 5 = 1 over 5 | When it comes to the -2x over 5 = -14 over 5, you will need a calculator for it. |
| -3=m+3 | Subtract 3 from both sides You get -6=-m Divide both by m which is 1, x=6 |
| 2 - 3x +4 + 6x =12 |
