Given: 2-%283x-20%29=4%28x-2%29
2-3x%2B20=4x-8, distribute
2%2B20%2B8=4x%2B3x, combine similar terms
30=7x
cross%2830%294.2857%2Fcross%287%29=cross%287%29x%2Fcross%287%29, divide 7 to isolate x
x=4.2857
Check, go back to given:
2-%283%2A4.2857-20%29=4%284.2857-2%29
2-%2812.8571-20%29=4%282.2857%29
2-%28-7.1429%29=9.1428
2%2B7.1429=9.1428
9.1429%3E=9.1428, close enough! we round it off the value of x.
