Question

me ayudaaaaaaaannnn

$\left \{ {{y=5x -2} \atop {y=x + 1}} \right.$

Answer 1

Oscar,

y = y

Siendo asi...... 5x -2 = x + 1

Reduciendo términos semejantes .... 5x - x = 1 + 2 ..... 4x = 3

Despejando incógnita .... x = 3/4

Comprobando

5(3/4) - 2 = 15/4 - 8/4 = 7/4

3/4 + 1 = 3/4 + 4/4 = 7/4

7/4 = 7/4  OK
