6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8
54 / 9 = n n = 6
log9(x)=2 x=9^2 x=81
4x+9=25 4x+9=25-9 4x/4=1 16/4=4 4x+9=26 4(4)+9=25 16+9=25 The answer is 4
X=45
X = 32
y - 4 = 9 y - 4 + 4 = 9 + 4 y = 13
10
2/9+4/9=6/9, which equals 2/3
4
x is 9.
(4/9) x = That's not an equation. If there were a number after the 'equals' sign, then we could calculate the value of 'x'. But as it is, there's no question there, so there's nothing to solve.
4 + 4 +1
You would do it it by oppisites. 3+2+4=9 which equals C.
9=4a+13 9-13=4a -4=4a -4/4=a -1=a a=-1
172=x
It equals 4 over 9. 4/9
