Answer:
So the answer to your question would be w=3 and w= -1/5.
Step-by-step explanation:
So, first you add -9 to both sides of the equation. 9+ -9=0, so that cancels each other. -7+-9=-16. So, now the equation is -2 (5w-7)= -16. The second step would be that you divide each side of the equation by -2. So, -2 (5w-7) divide by -2 would be 5w-7 and -16 divide by -2 would be 8. So, now the equation is (5w-7)=8. So, then we have to solve for the absolute value. So, answer could be 5w-7=8 or 5w-7= -8. For possibly 1, you add 7 to both sides to get 5w=15. The sevens cancels each other and 8+7=15. Then, you divide 5. 5w/5 = w, since the fives cancel each other and 15/5=3. So for possibly 1 the answer is w=3. For possibly 2, you add 7 to both sides of the equation to get 5w= -1. Then you divide by 5 to get w= -1/5. Since -1/5 can't be reduced anymore it will just stay the same. Hope you have a nice day.
