1. Para que le hagan un pantalón a Alberto se utilizan 3 cortes de tela cuyas medidas son: 1 1/2 * m; 4/5 * m * y * 3/6 mSi el rollo mide 4 metros, ¿cuánta tela sobra?

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
