10×+73=7 solve two step equations by using inverse operations. and use inverse operations to solve the equations

x=-67/10

Step-by-step explanation:

What you have to do is first subtract 73 from both sides. that makes it 10x=7-73. That is 10x=-67. Then divide both sides by 10. That is x=-67/10

Can I get brainliest

x= -67/10 hope it help

Step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can
