Question

What is the y value in the equation -3x + 6y = 18?

  1. y equals fraction numerator 18 plus 3 x over denominator 6 end fraction
  2. y equals fraction numerator 18 minus 3 x over denominator 7 end fraction
  3. y equals fraction numerator negative 18 plus 3 x over denominator 3 end fraction
  4. y equals fraction numerator 18 x minus 6 over denominator 6 end fraction

hintHint:

try to send each part on l.h.s. to r.h.s.
except y so you get y .

The correct answer is: y equals fraction numerator 18 plus 3 x over denominator 6 end fraction


    Given
    -3x + 6y = 18
    step 1 :
    send -3x to rhs so it becomes +3x
    6y = 18 + 3x
    step 2 :
    now 6 is in multiply with y when it go to rhs it become divide
    y = ( 18 + 3x ) / 6
    so , value of y is ( 18 + 3x ) / 6  .

    Solve , equation for y .
