a)até d)

a)3×+10=85
b)5×+18=33
C)6×-2=4×+16
d)7×-24=3×+20​

Answer 1

→ Cálculo :

A) 3x + 10 = 85

3x = 85 - 10

3x = 75

x = 75 ÷ 3

x = 25

B) 5x + 18 = 33

5x = 33 - 18

5x = 15

x = 15 ÷ 5

x = 3

C) 6x - 2 = 4x + 16

6x - 4x = 16 + 2

2x = 18

x = 18 ÷ 2

x = 9

D) 7x - 24 = 3x + 20​

7x - 3x = 20 + 24

4x = 44

x = 44 ÷ 4

x = 11

Answer 2

Oiie!

a)

3x + 10 = 85

3x = 85 - 10

3x = 75

x= 75/3

x= 25

b)

5x + 18 = 33

5x = 33 - 18

5x = 15

x= 15/5

x= 3

c)

6x - 2 = 4x + 16

6x - 4x = 16 + 2

2x = 18

x= 18/2

x= 9

d)

7x - 24 = 3x + 20

7x - 3x = 20 + 24

4x = 44

x= 44/4

x= 11
