If 7 out of 10 candles are lit, then seven-tenths of the candles are lit. The tenths place is directly to the right of the decimal. Since you have seven-tenths, the tenths place will be seven. So, the decimal that represents the candles lit will be 0.7



Since bases i.e 6 are same exponents are equal
4x+10= 3x-3
4x-3x = -3-10
x= -13
