Let x be a number.
16=(3+x)*4
16=12+4x
16-12=12+4x-12
4=4x
4/4=4x/4
1=x
Therefore a number is 1.
((2n + 8)) x 5 = 6n + 12ie 10n + 40 = 6n + 124n = -28n = -7(both equations total -30)
it is 10 times larger (of the number that was multiplied by 10 or added a zero at the end)
The two numbers that are being added are each called addends, and the result is called a sum.
If: -3*(x+8) = -21 Then: x = -1
7
6x + 18 = 4 - x 7x + 18 = 4 7x = -14 x = -2
The sum is the total when numbers are added together, the product is the total when they are multiplied.
4(8+2x)=5x+1132+8x=5x+118x-5×=11-323x=-213 3=-7Therefore the number is -7
The number is 48.
((2n + 8)) x 5 = 6n + 12ie 10n + 40 = 6n + 124n = -28n = -7(both equations total -30)
When you add a number to another number the result is their sum
Let the number be x: 2(2x+4) = 3x+4 4x+8 = 3x+4 4x-3x = 4-8 x = -4
17 and 7
It is called the sum
you call is the sum
there are 12 boys in the class
The resulting number is their "sum".
