What's the number? 4.9 minus the product of 2.9 and 0.5 is one less than five times X What is the number eight times plus ten equals twelve times minus six? The product of 4.9 minus 2.9 and 0.5 is 1.65 less than five times of X

1. How much is the number that eight times plus ten equals twelve times minus six? Let a number be X;
　　8x+10=12x-6
　　12x-8x=10+6
The solution is that the product of x = 42,4.9 minus 2.9 and 0.5 is 1.65 less than five times of X
　　5x-1.65=4.9-2.9×0.5
　　5x-1.65=4.9-1.45
　　5x=5.1
　　x=1.02
