Answer:
p=-7/3=-2.333
Explanation:
Step 1: You can rearrange the equation to get a simpler and easier form to understand what to do next. In this case, rearranging it while keeping the same question would end up in -2-(6/7*p)=0
Step 2: Simplify 6/7. That would be in getting zero as your answer, but the equation form would be -2-(6/7*p)=0. Then subtract the fraction from a whole as -2=-2/1=(-2*7)/7 while adding up the two equivalent fractions, (-2 • 7 - (6p))/7=(-6p - 14)/7.
Step 3: Pull out the like factors. So to make it easier, you would have to solve -6p - 14 = -2 • (3p + 7). This would get you the equation at the end (-2 • (3p + 7))/7=0.
Step 4: When a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero. Now, to get rid of the denominator, you must multiply both sides of the equation by the denominator.
Here's how:
-2•(3p+7)
————————— • 7 = 0 • 7
7
Now, on the left hand side, the 7 cancels out the denominator, while, on the right hand side, zero times anything is still zero. The equation now takes the shape :
-2 • (3p+7) = 0
Since it's now time to solve each equation individually, it would be -2=0, which we know isn't true and the right answer. That leaves 3p+7=0. So subtract 7 from both sides to get 3p=-7. And with last thing to do, divide both sides by 3 to get your final answer of p = -7/3, your final answer. Hope this helps :)
