Question

Select all the equations were x=3 is a solution ?
choose 2 answers

a)x+4=7.
b) x/9=3
c)5-x=2
d)8x=32
e)x-10=7​

Answer 1

Step-by-step explanation:

b is the right answer

If we think that b is 3/9 after cancellation it is 3

Answer 2

Answer :-

• a) x + 4 = 7
• $\sf x = 7 - 4$
• x = 3

_____________

• b) $\sf \frac{x}{9} = 3$
• x = 9 × 3
• x = 27

_____________

• c) 5 - x = 2
• 5 - 2 = x
• 3 = x
• x = 3

_____________

• d) 8x = 32
• $\sf x = \frac{\cancel{32}^{\: \: 4}}{\cancel8}$
• x = 4

_____________

• e) x - 10 = 7
• x = 7 + 10
• x = 17

_____________

Hence, equation (a) and (c) is right

I hope it helps you ❤️✔️
