3(r-6) +2 = 4(r+2) -21
3r - 6r +2 = 4r +8 -21
-3r +2 = 4r -13
2 = 7r -13
15 = 7r
r =
r = 7.5
3r - 6r +2 = 4r +8 -21
-3r +2 = 4r -13
2 = 7r -13
15 = 7r
r =
r = 7.5
For this case we must find the value of the variable "x" of the following equation:
We rewrite the equation as:
We take the logarithmic base 10 from both sides of the equation to remove the variable from the exponent.
The logarithmic base 10 of 10 is 1.
