7)x+3x=120
8) 1325+3290×=932+111,50x
qual é o resultado de todos

Answer 1

a) x+3x=24
4x=24
x=6
b) 2x+3x=?
5x=0
x=0
c) x+x+1+3x=81
5x=80
x=16

d) 10x+100=15x+20
10x-15x=20-100
-5x=-80
x=16

e) x+65=370-65
x= 305-65
x= 240

f) x+4x= 360
5x=360
x=72
g) x+3x=120
4x=120
x=30
h) 1325+3290x=932+11150x
3290x-11150x=932-1325
-7860x=-393
x=393/7860
x= 131/2620

Answer 2

Olá.

1) x + 3x = 24
4x = 24
x = 24 ÷ 4
x = 6

2) 2x + 3x = 0
5x = 0
x = 0/5
x = 0

3) x + x + 1 + 3x = 81
x + x + 3x = 81 - 1
5x = 80
x = 80 / 5
x = 16

4) 10x + 100 = 15x + 20
10x - 15x = 20 - 100
-5x = -80 , *(-1)
5x = 80
x = 80 / 5
x = 16

5) x + 65 = 370 - 65
x = 370 - 65 - 65
x = 370 - 130
x = 240

6) x + 4x = 360
5x = 360
x = 360 / 5
x = 72

7) x + 3x = 120
4x = 120
x = 120 / 4
x = 30

8) 1325 + 3290x = 932 + 111,50x
3290x - 111,50x = 932 - 1325
3178,50x = -393
x = -393 / 3178,50
x = -0,124

ou

1325 + 3290x = 932 + 223x / 2 , mmc (2)
2650 + 6580x = 1864 + 223x
6580x - 223x = 1864 - 2650
6357x = - 786
x = -786 / 6357
x = -0,124

Espero ter ajudado .
