9x es la respuesta porqe el -2xy se va por el
For the first problem the answer is -5/2
2x−7+10=−2
Step 1: Simplify both sides of the equation.
2x−7+10=−2
2x+−7+10=−2
(2x)+(−7+10)=−2
(Combine Like Terms)
2x+3=−2
Step 2: Subtract 3 from both sides.
2x+3−3=−2−3
2x=−5
Step 3: Divide both sides by 2.
2x/2=−5/2
x=−5/2
Answer:
x= -5/2
the amount of gold present is - 9/10 of an ounce of gold
from this gold they have to split into groups of 1/6 ounce each
so we have to divide 9/10 ounce in to groups of 1/6
for this we have to divide 9/10 by 1/6

when dividing fractions we mutiply the first fraction by the reciprocal of the second fraction
reciprocal of 1/6 is - 6/1

so the number of groups that can be made is 5 whole groups with 0.4 ounce of gold remaining
the whole number of groups that can be made - 5
