Q. In \(45\) years, Gabriela will be \(4\) times as old as she is right now.\newlineHow old is she right now?
  1. Equation setup: Let's denote Gabriela's current age as GG. According to the problem, in 4545 years, Gabriela will be 44 times as old as she is right now. We can write this as an equation:\newlineG+45=4GG + 45 = 4G
  2. Isolate G: Now we need to solve for G. We can do this by getting all the terms with G on one side of the equation and the constants on the other side:\newline4G−G=454G - G = 45
  3. Combine like terms: Simplify the equation by combining like terms:\newline3G=453G = 45
  4. Divide by 33: To find GG, we divide both sides of the equation by 33: \newlineG=453G = \frac{45}{3}
  5. Find Gabriela's current age: Perform the division to find Gabriela's current age:\newlineG=15 G = 15
