Converting equationa to standard form

Question

1.      Y+1=-(x+3) 

 

2.      -10x-y=-5 

 

3.      -4-2y=-x 

 

 

thank you!!!! 

Answer 1

Standard form of a linear equation is given by, Ax + By = C. Transform each equation into this form.

1. y + 1 = -(x+3) 

   y + 1 = -x -3           (Distribute the negative sign)

   y = - x -3 -1             (Subtract 1 from both sides)

  x + y = -4       (Add x to both sides then simplify)

 

2. -10x-y=-5

10x + y = 5       (Multiply both sides by -1.)

 

3. -4-2y=-x

x -2y = 4            ( Add x to both sides and add 4 to both sides.)
