Respuesta :
-2(7-y)+4=-4
Multiply the bracket by -2
(-2)(7)(-2)(-y)+4=-4
-14+2y+4=-4
Combine like terms:
-14+4+2y=-4
-10+2y=-4
Move -10 to the other side. Sign changes from -10 to +10.
-10+10+2y=-4+10
2y=6
Divide by 2 for both sides.
2y/2=6/2
Cross out 2 and 2, divide by 2 and then becomes: 1*1*y=y
y=3
Answer : y=3
