How do I solve the equation y=5/4x-7

Apr 3rd, 2015

First set the equation equal to zero

0=(5/4)x-7

(add 7 to both sides)

7=5/4x

(times each side by 4/5) (This will cross out 5/4 on the right side of the equation, leaving just x)

7*4/5 =x

28/5=x

You have solved for x

Now you can solve for y

Simply take the original equation and plug in the x value

y= (5/4)(28/5) -7

y=(140/20)-7 (you can simplify 140/20)

 y= 7-7

y=0

This is how you would do this problem, If this is not what the question was asking. Please tell me and I will know what to do.

Thanks
