Question

ayudaaaa necesito esto para hoy!!!!
y+2.(y+10)+2y+5=75
2z+6=2.(z+3)
3-5n=-95-3n
c-3=2c-46
2v+2.(v+1)+2v=20
2.(t+3)-4t=16

Answer 1

(y+2)(y+10)+2y+5=75
y^2 +10y + 2y + 20 +2y +5=75
y^2 +14 y =50
y^2+14y-50=0
por formula general:
y1= 2.94985
y2= -16.94985

2z + 6=2(z+3)
2z+6=2z +6

3-5n = -95-3n
98=2n
n=49

c-3=2c-46
3c=43
c=14.33333

2v+2v+2+2v=20
6v +2=20
6v=18
v=3

2t+6-4t=16
-2t= 10
-t=5
t=-5
