Question

Solve. 13-0.3(j-9)=0.9(11j-9)

Answer 1

Use the distributive property to expand both sides. Then add and subtract quantities from both sides to get j alone on one side. If there is a coefficient for j that does not equal 1 at that point, divide both sides by the coefficient and you'll be left with j = <the answer>.

If you don't remember what the distributive property is:
\[a(b-c) = ab -ac \]

Hint: don't forget about subtracting negative numbers!
\[-a(b-c) = -ab -(-ac) = -ab + ac\]

Answer 2

j=2.3333
