What is the solution to the equation -m+kx=j

  X = (J+M)/K

Step-by-step explanation:

Undo what has been done to the variable, in reverse order. The variable has been multiplied by K and M subtracted from the result. So, we first add M (to undo the subtraction), then we divide by K (to undo the multiplication).

  KX = J +M . . . . . . M added to the given equation

  X = (J + M)/K . . . . the result of that is then divided by K

___

Since these are all capital letters, we might assume they represent vectors and/or matrices. If so, the "divide by K" step needs to be "multiply on the left by K^-1, the matrix inverse of K."

Then your solution looks like

  X = K⁻¹·(J + M)

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
