What is the value of x , if y = 2<br>in the given equation ;<br><br>5x + 2y = 9​
Strike441 [17]
<h3><u>Explanation</u></h3>
  • Given the equation.

5x + 2y = 9

with given condition where y = 2.

Therefore, substitute the value of y in the equation.

5x + 2(2) = 9 \\ 5x + 4 = 9

  • Solve the equation for x-term.

5x = 9 - 4 \\ 5x = 5 \\ x =  \frac{5}{5}  \longrightarrow  \frac{1}{1}  \\ x = 1

  • Check the answer by substituting both x-value and given y-value in the equation.

5x + 2y = 9 \\ 5(1) + 2(2) = 9 \\ 5 + 4 = 9 \\ 9 = 9 \longrightarrow  \bf{true} \:  \green{ \checkmark}

Hence, the value of x is 1.

<h3><u>Answer</u></h3>

<u>\large{x = 1}</u>
