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 is the y value of x - y equals 120 x plus y equals 150?

What plus 150 equals 180?
To find the number that plus 150 equals 180, you can set up the equation: x + 150 = 180. By subtracting 150 from both sides, you find that x = 30. Therefore, 30 plus 150 equals 180.
What is 4x-7 equals x plus 59?
120
What percent is 72 of 150?
You would formulate this problem X/100 * 150 = 72 and solve for X.
What is 150 plus something equals 500?
Let that something be x: 150+x = 500 x = 500-150 x = 350
If 28 plus 2x equals 120 what is the value of x?
28 + 2x = 120 2x = 120 - 28 2x = 92 x = 92/2 x = 46
-150-9x equals 10x plus 21 what is x?
-171 = 19x so x = -9
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 ).
