Question

Resultado de la ecuación de 4x + 3(y–1)=5 y 3(y–1)=2x–7

Respuesta xfissss ❤❤

Answer 1

4x+3(y–1)=5    
4x+3y + 3 = 5
4x+3y = 2

3(y–1)=2x–7 
3y-3 = 2x-7
7-3=2x-3y
4=2x-3y

4x+3y = 2  .....,,. I
2x-3y = 4  .........II
''''''''''''''''''''''
6x = 6
x = 6/6
x = 1   .........III

III en I

4x+3y = 2
4(1) +3y = 2
4+3y = 2
3y = 2-4
3y = -2
y = -2/3

CS = (1; -2/3)
