Answer 2

Explanation

• 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 = (5)/(5) \longrightarrow (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.
