Question

x-2{5+3x-[5x-3(6+x)]-3x}=-3​

Answer 1

Respuesta:

x = $\frac{43}{5}$

Explicación paso a paso:

x-2{5+3x-[5x-3(6+x)]-3x}=-3​

x-2{5-[5x-3(6) -3(x)]}=-3​

x-2{5-[5x-18 -3x]}=-3​

x-2{5-[2x-18]}=-3​

x-2{5-2x+18}=-3​

x-2(23-2x)=-3​

x-2(23)-2(-2x))=-3​

x - 46 + 4x = -3

5x -  46 = -3

5x = 46 - 3

5x = 43

x = 43/5 = 8,6
