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 + 4 +1
(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.
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
