Question

esta es una ecuación 3x+2=32
2x+80=440
7x-4=171

Answer 1

Respuesta:

3×+2=32

3×=30

×=10

2×+80=440

2×=440-80

2×=360

×=180

7×-4=171

7×=171+4

7×175

×=25

Answer 2

3x + 2 = 32

3x = 32 - 2

3x = 30

x = 30 / 3

x = 10

2x + 80 = 440

2x = 440 - 80

2x = 360

x = 180

7x - 4 = 171

7x = 171 + 4

7x = 175

x = 175 / 7

x = 25
