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
