Isolate variable g: First, we want to isolate the variable g on one side of the equation. To do this, we can start by adding 0.9 to both sides of the equation to eliminate the −0.9 on the right side.−0.4+0.9=3g−0.9+0.9
Addition on left side: Now, we perform the addition on the left side of the equation. 0.5=3g
Multiply by 3: Next, we need to solve for g by multiplying both sides of the equation by 3 to get rid of the denominator.3×0.5=g
Find value of g: Finally, we perform the multiplication on the left side to find the value of g.1.5=g
