-2(7-y)+4= -4 -14-2y+4= -4
-10-2y= -4
-2y=6
y=-3
Each side of the equation should have been divided by–2 before the second step.
When using the Distributive Property in the second step, the second term should have been positive 2y.
In the fourth step. – 10 was subtracted incorrectly on the right side.
In the last step, each side should have been multiplied by —2, not divided.
brrect solution is y=
