Question

resolva as equações:
a. x + 15 = 35

b. 3y - 4 = 28

c. 2. (w - 2) = 16

d. 3z - 10 = z + 60​

Answer 1

a. x + 15 = 35

x = 35 - 15

x = 20

b. 3y - 4 = 28

3y = 28 + 4

3y = 32

y = 32/3

c. 2. (w - 2) = 16

2w - 4 = 16

2w = 16 + 4

2w = 20

w = 10

d. 3z - 10 = z + 60​

3z - z = 60 + 10

2z = 70

z = 70/2

z = 35
