Pvrr Me ajudemm

Answer 1

a)10x+15=24+x
10x-x=24-15
9x=9
x=1

b)2x+4x-x=2x-2
2x+4x-x-2x=-2
3x=-2
x=-2/3

c)15x+10=4-4x-10
15x+4x=4-10-10
19x=-24
x=-24/19

d)4x-8+2x-6=1
4x+2x=1+6+8
6x=15
x=15/6
x=2,5

e)8+7x+21=15x-3
7x-15x=-3-21-8
-8x=-32
multiplica por (-1)
8x=32
x=32/8
x=4

f)7+2x+6=8-5x+5
2x+5x=8+5-6-7
7x=0
x=0/7
x=0

g)8x-24+10-2x=-x
8x-2x+x=24-10
7x=14
x=14/7
x=2

j)-4x+6-10+5x=6x+9
-4x+5x-6x=9-6+10
-5x=13
multiplica por (-1)
5x=-13
x=-13/5
x=-2,6

Espero ter ajudado!
