Question

b. 4x + 3y = 24
5x-2y=7​

Answer 1

Respuesta:

x = 3

y = 4

Explicación paso a paso:

A 4x + 3y = 24

B 5x - 2y =   7​

5A - 4B

5(4x + 3y = 24)

-4(5x - 2y =   7​)

20x + 15y = 120

-20x +  8y = -28

------------------------

          23y = 92

              y = 92 / 23

              y = 4

4x + 3y = 24

4x + 3(4) = 24

4x +12 = 24

4x = 24 - 12

4x = 12

x = 12 / 4

x = 3
