Step-by-Step Solution

This linear equation problem can be solved by isolating the variable x x . Here's how we proceed:

Step 1: Multiply both sides of the equation by the reciprocal of the coefficient of x x . In this case, the coefficient is 49 \frac{4}{9} , so its reciprocal is 94 \frac{9}{4} .

94×49x=18×94\frac{9}{4} \times \frac{4}{9} x = 18 \times \frac{9}{4}

This simplifies to:

x=94×18x = \frac{9}{4} \times 18

Step 2: Perform the multiplication on the right side of the equation.

x=9×184x = \frac{9 \times 18}{4}

Simplify the expression:

x=1624x = \frac{162}{4}

x=40.5x = 40.5

Therefore, the value of x x that satisfies the equation is 40.5 40.5 .

Answer

40.5 40.5
