You want to use the addition property, so you need to ADD each term. Just change the minuses to pluses, making sure you keep the negative with the number

5x-8x-7y+y =

5x + -8x + -7y +y

If 6a=5b, what are the following ratios? a+b/b

lidiya [134]

Our Equation is

$6a=5b$

which means

$a = 5b/6$

Now we have to find this ration

$\frac{a+b}{b}$

Inserting value of a into this equation

$=\frac{\frac{5b}{6}+b}{b}$

$=\frac{\frac{11b}{6}}{b}$

$=\frac{11b}{6b}$

$=\frac{11}{6}$
