anonymous · Answer

Yes i know that 4 times x = 4x and 4 times 1 = 4 but whats next ? this is where im stuck

anonymous · Answer

$$\small4(x + 1) = -12 \implies 4(x) + 4(1) = -12 \implies 4x + 4 = -12\implies 4x = -16 \implies x = -4$$$$\Huge OR$$$$4(x + 1) = -12 \implies x + 1 = -3 \implies x = -4$$

anonymous · Answer

wouldnt 4x + 4 = 8x ?  i dont get it ...

anonymous · Answer

Where are you getting the 8x from?

anonymous · Answer

Cause if you had 4x + 4 wouldnt that =  8x ?

anonymous · Answer

No. 4x and 4 are not like terms since 4 does not have an x. Plus, there is a -12 on the other side.

anonymous · Answer

It would onyl equal 8x if it were 4x + 4x.

zzr0ck3r · Answer

4 apples + 4 apples = 8 apples
4apples + 4 does not equal 8 apples

zzr0ck3r · Answer

its sort of odd because of the way we speak. Like if i say I have 4 apples and someone says add 4. You assume they mean add 4 apples. but with math we cant assume:)
