Question

SI: 2(A-1)+3(A+2)=-26, Ademas: -13B + 5B- -64 y M = -3A+2B Entonces el valor de X en la ecuaci´on: -4X+10= M es.

Answer 1

2(A - 1) + 3(A + 2) = -26
2A - 2 + 3A + 6 = -26
5A = -30
A = -6

-13B + 5B = -64
-8B = -64
B = 8

M = -3A + 2B
M = -3(-6) + 2(8)
M = 18 + 16
M = 34

⇒
M = -4X + 10
34 = -4X + 10
24 = -4X
-6 = X
