Ответ:
5 - 3(4x + 7) = 2(x + 5) [Given]
5 - 12x + 21 = 2x + 10 [Distribute]
5 - 12x +12x + 21 = 2x + 10 +12x [Cancel]
5 + 21 = 2x + 10 + 12x
26 = 10 + 14x [Combine like terms]
26 - 10 = 10 + 14x - 10 [Cancel]
16 = 14x
16/14 = 14x/14 [Divide]
16/14 = x
x = 1 2/14
x = 1 1/7
Hopefully this helps?
Ответ:
Always the same variable.
Step-by-step explanation:
When the question says "x is always constant", it means that the x variable does not change, and it is always the same number.
