2r-20 is the answer combining the like terms and solving.
Let's solve your equation step-by-step.
−2(4k−7)=22−8k
Step 1: Simplify both sides of the equation.
−2(4k−7)=22−8k
(−2)(4k)+(−2)(−7)=22+−8k(Distribute)
−8k+14=22+−8k
−8k+14=−8k+22
Step 2: Add 8k to both sides.
−8k+14+8k=−8k+22+8k
14=22
Step 3: Subtract 14 from both sides.
14−14=22−14
0=8
So, the answer is 0=8.
I'm doing the same thing right now and I'm lost.
$76.80 minus 12 1/2 is $64.30.
It’s an obtuse triangle, this is because none of the sides/angles are equal to one another. Hope this helped you
