Solve by Substitution :
// Solve equation [1] for the variable

![[1] x = y + 5](https://img.qammunity.org/2023/formulas/mathematics/high-school/q9v0bxhdwsvd3eu8bjjqthf5q39bkw4vox.png)
// Plug this in for variable
in equation

![[2] 3*(y +5) - 2y = 12 \\ [2] y = -3](https://img.qammunity.org/2023/formulas/mathematics/high-school/ob8bxihyjwbohb4m87iqfm5gup4i7s21fa.png)
// Solve equation
for the variable

![[2] y = - 3](https://img.qammunity.org/2023/formulas/mathematics/high-school/9rx306e5cbencvsa67zghubcmbti19156z.png)
// By now we know this much :

// Use the y value to solve for


Solution :
