Question

Resolva as equaçoes do 1 Grau a)5X - 10 = 3X + 20
b)20X - 15 = 10X + 35
c)6X+10 = 4X + 50
d) 7X-11 = 3X + 33
​

Answer 1

Explicação passo-a-passo:

a)5X - 10 = 3X + 20

5x-10=3x+20

5x-3x=20+10

2x=30

x=30/2

x=15

b)20X - 15 = 10X + 35

20x-15=10x+35

20x-10x=35+15

10x=50

x=50/10

x=5

c)6X+10 = 4X + 50

6x+10=4x+50

6x-4x=50-10

2x=40

x=40/2

x=20

d) 7X-11 = 3X + 33

7x-11=3x+33

7x-3x=33+11

4x=44

x=44/4

x=11

Espero ter ajudado!
