Question

me ajudem e para hj

3x + x + x =25

4x+2x -5=25

5x -3 - 2x = 9

4n +2n +6n +10= 22

5x - 3x -17 =31

7y +y +2y-50=100

50h +30h+20h -50=50

3n-n-n=20

5x-4x-10=30

9x +5x -4x =40

Answer 1

1) 3x + x + x =25
5x=25
x=25/5
x= 5

2)6x=25+5
6x=30
x=30/6
x=5

3) 3x=12
x=12/3
x=4

4) 12n=22-10
12n=12
n=1

5)2x=31+17
2x=48
x=48/2
x= 24

6)10y=100+50
10y=150
y=150/10
y=15

7)100h=100
h=100/100
h=1

8) n=20

9)x= 40

10) 10x=40

x=40/10
x=4

Espero ter ajudado.
