When will two persons aged 45 and 50 equal 150 using this equation X plus x plus 5 equals 150?
In 27.5 years. [By the way, I think you mean x+x+95=150.] Let x be the number of years in the future when the sum of their ages will be 150. In x years, the younger person will be 45+x and the older will be 50+x. The sum of their ages will be 150, and the equation to find x is given by: (45+x)+(50+x)=150 Now solve for x: (45+x)+(50+x)=150 95+2x=150 2x=150-95=55 x=55/2=27.5 So the sum of their ages will be 150 in 27.5 years. The younger person will be 45+27.5=72.5 and the older person will be 50+27.5=77.5.

What plus something equals 300?
To find what plus something equals 300, you can represent it mathematically as ( x + y = 300 ), where ( x ) is the known value and ( y ) is the unknown value. For example, if ( x ) is 150, then ( y ) would be 150, since ( 150 + 150 = 300 ). You can replace ( x ) with any number less than 300 to find the corresponding ( y ).
