Question

Por favor me ajudem

a) 12(x-3)+1=6(x+1)-5
b) 5y-6=2(y+9)
c) 6(-3m+5)-4(2m+2)=-3x(6+8m)
d)6x-17=13(x-1)-4

Answer 1

a) 12(x-3)+1=6(x+1)-5
12x-36+1=6x+6-5
12x-6x=6-5+36-1
6x=36
x=36/6
x=6
b) 5y-6=2(y+9)
5y-6=2y+18
5y-2y=18+6
3y=24
y=24/3
y=8

c)6(-3m+5)-4(2m+2)=-3x(6+8m)
-18m+30m-8m-8m=-18x-24m
30m+24m-18m-8m-8m=18x
20m=18x
m
d)6x-17=13x-13-4
6x-13x=-13-4+17
-7x=0
x=0/-7
x=0
