7x - 8 = 3x + 4
4x - 8 = 4
4x = 12
x = 3
Check it.
21 - 8 = 9 + 4
It checks.
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
3x+32=4x-15 3x-4x=-15-32 x=-47
6n - 3n which simplifies to 3n.
x - 2 = 7 + x/4 4x - 8 = 28 + x 3x = 36 x = 12
x-4=8+x/5 5(x-4)=5(8+x/5) 5x-20=8+x 4x=28 x=7
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
3x+32=4x-15 3x-4x=-15-32 x=-47
6n - 3n which simplifies to 3n.
Let the number be x:- 4x+40 = 100-x => 5x = 60 => x = 12 So the number is 12
Decreased
Eleven
The equation can be expressed as: ( 9 - 3x = 5(y + 5) ), where ( x ) is the unknown number being decreased and ( y ) is the unknown number being summed with five. This states that nine decreased by three times ( x ) is equal to five times the sum of ( y ) and five.
Australia's population has increased
If force is increased and pressure remained the same, then the area must have been decreased.
Yes because one number has been increased by a 1/4 while the other number has been decreased by a 1/4 So 3*80 = 240 and 4*60 = 240
x+5 = 7 - (2x) 3x = 2 x = 2/3 The number is 2/3
