X + y = 92 and y = 3x - 4

Advocard [28]

∑ Hey, eduardolozanosalgado ⊃

Answer:

x=24 , y=68

Step-by-step 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 : $x=24,\:y=68$
