Answer 1

Solve -5y +8 = -3y +10
I need to solve for y but having issues remembering what the steps are..

 

This is one equation with one unknown . The unknown is y

 

simply rearrange by adding +5y on both sides,

 

+5y-5y+8=-3y+5y+10, 8=2y+10 now add -10 to both sides of the equation

 

-10+8=2y+10-10, -2=2y divide both sides by -2

 

(-2/-2)=(2y/-2), 1=-y, or y=-1

 

Check by substituting y =-1 in the original equation

 

-5y +8 = -3y +10, -5(-1)+8 = -3(-1) +10, 5+8=3+10, 13=13 checks

 

y=-1 is the final answer

Answer 2

-5y + 8 = -3y + 10      Add 3y to both sides of the equation.

-2y + 8 = 10                Subtract 8 from both sides of the equation.

-2y = 2                         Divide both sides by -2.

y = -1
