Question

Given that y = 4x – 3, work out the value of x when y = 11

Please help! How do I do this?!​

Answer 1

Answer:

Given that y=4x−3y=4x−3, work out the value of xx when y=11y=11

I don't get this because i can't think of a number that you can multiply by 4 then subtract 3 to get 11 or am i missing something?

Answer 2

⠀⠀⠀⠀⠀${Given, y = 4x-3}$

⠀⠀⠀⠀⠀⠀⠀$And \: y = 11$

⠀⠀⠀⠀⠀$So, 4x-3 = 11$

⠀⠀⠀⠀⠀ ⇒ 4x = 11-3

⠀⠀⠀⠀ ⠀⇒ 4x = 8

⠀⠀ ⠀⠀⠀⇒ x = 8/4

⠀⠀ ⠀⠀⠀⇒ x = 2

$Therefore,\:the\:value \:of\: x\: is\: 2.$
