Answer:

x=24 , y=68

Explanation:

Given:

`\mathrm{\begin{bmatrix}x+y=92\\ y=3x-4\end{bmatrix}}`

Solution:

Substitute:
`\mathrm{y = 3x-4}`

`\begin{bmatrix}x+3x-4=92\end{bmatrix}`

Isolate x for 4x - 4= 92 : x = 24

Substitute : x = 24

`y=3\cdot \:24-4`

`y=64`

Hence, the solutions are :
`x=24,\:y=68`
