Question

−12.7=y−3.4
Can you guys please help me solve this. Thanks!

Answer 1

For this case we have the following equation:
 $-12.7 = y-3.4$
 From here, we must clear the value of y.
 For this, we follow the following steps:

 1) we add 3.4 on both sides of the equation:
 $-12.7 + 3.4 = y-3.4 + 3.4$

 2) We rewrite the right side of the equation:
 $-12.7 + 3.4 = y + 0 -12.7 + 3.4 = y$

 3) We do the algebraic sum of the left side of the equation:
 $-12.7 + 3.4 = y -9.3 = y$

 Therefore, the solution of the equation is:
 $y = -9.3$

 Answer:
 y = -9.3
