Solve the following equation for the unknown variable: 1.3E + (–7.54) = 7.54.

1.3E + (–7.54) = 7.54

To solve for E, first add 7.54 to both sides of the equation:

1.3E = 7.54 + 7.54
1.3E = 15.08

Now, divide both sides by 1.3 to solve for E:

E = 15.08 / 1.3
E = 11.6

So, the solution to the equation is E = 11.6.
