5x+(-4)=7x-5 show step by step

Step-by-step explanation:

First you have to add 4 to both sides--5x-4+4=7x-5+4

Now you have 5x=7x-1

Next you subtract 7x from both sides--5x-7x=7x-1-7x

Next you simplyfiy -2x=-1

Now divide by -2 on each side--2x/2=-1/2

So your answer should be--x=1/2

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
