2n + 4 = 25
4 ×n=25
If the unknown number is q then: 2q+25 = 72
2z+9
*Write and it's 2x+6 x being the number
1+x2=5 x+2
It is: 2x+11 = -1 and the vaue of x works out as -6
It is: 3x = 2x+8 and the value of x is 8
If the unknown number is q then: 2q+25 = 72
negative 2
3
8+2n
8 more than twice a number d
Qx2+4
2x+3=11
2n+12=x
2z+9
*Write and it's 2x+6 x being the number
If you want "the number" write 5 + 2X = 7 2X = 2 X = 1. So "five more than twice of one is 7.
