X+3=8
n+3 the sum of a number and three means a number plus three.
in the equation 3+4=7, 3 and 4 are the addends. 7 is the sum.
The second number in an addition equation is called the "addend." In an equation like 3 + 5 = 8, the number 5 is the addend that follows the first addend, which is 3. The result of the addition is known as the "sum."
It means that some number is having 14 added to it. The sum of 3 and 14, for example is 3 + 14.
If: 9+x = 3 then x = -6
3(x + 12)
It is an algebraic equation.
n+3 the sum of a number and three means a number plus three.
in the equation 3+4=7, 3 and 4 are the addends. 7 is the sum.
3 (n + 7) = 16
It means that some number is having 14 added to it. The sum of 3 and 14, for example is 3 + 14.
If: 9+x = 3 then x = -6
The equation for three times the sum of a number ( x ) and five times the number can be expressed as ( 3(x + 5x) = 36 ). Simplifying this gives ( 3(6x) = 36 ), or ( 18x = 36 ). To solve for ( x ), divide both sides by 18, resulting in ( x = 2 ).
There are two solution: -3 and +2.
I must change your description to read " ... 3 times as much as ... ".Then the equation is 0.33 N = 3 x (0.17 N) . The equation has no solution. That means that no numbercan make the equation a true statement.
i dont now
No. The sum of its digits, 5 + 3 + 1, is divisible by 3, which means the number itself is also divisible by 3.
