Q. Which equation has the solution

x=6

?

\newline

2 x+9=-21

\newline

4 x-6=18

\newline

5 x+3=19

\newline

5 x+9=64

Identify Equation: We need to find which equation has the solution $x=6$ . To do this, we will substitute $x=6$ into each equation and see which one holds true.
Equation $1$ Substitution: Substitute $x=6$ into the first equation: $2x+9=-21$ . $\newline$ Calculation: $2(6)+9 = 12+9 = 21$ . $\newline$ Check if $21$ equals $-21$ . $\newline$ $21$ is not equal to $-21$ .
Equation $2$ Substitution: Substitute $x=6$ into the second equation: $4x-6=18$ . $\newline$ Calculation: $4(6)-6 = 24-6 = 18$ . $\newline$ Check if $18$ equals $18$ . $\newline$ $18$ is equal to $18$ , so this equation could be the correct one.
Equation $3$ Substitution: Substitute $x=6$ into the third equation: $5x+3=19$ . $\newline$ Calculation: $5(6)+3 = 30+3 = 33$ . $\newline$ Check if $33$ equals $19$ . $\newline$ $33$ is not equal to $19$ .
Equation $4$ Substitution: Substitute $x=6$ into the fourth equation: $5x+9=64$ . $\newline$ Calculation: $5(6)+9 = 30+9 = 39$ . $\newline$ Check if $39$ equals $64$ . $\newline$ $39$ is not equal to $64$ .
