Find the value of x so that the function has the given value.j(x)=-4/5x+7;j(x)=-5

multiply 5 on both sides then move the variable to the left the your equation will look like. ... 25x=-4x+35
combine like terms aka 25x + 4x
then it will look like
29x=35
then divide 29 by bothe sides the 29 will cancel out so u have x only but no need to divide 35/29 leave the same .
answer is x=35/29

hope this makes sence
