“Simplify” it by collecting all of the constants on one side to calculate the variable/unknown on the other side.

$- 2.4 \cdot x + 11.8 = 29.8$ $-2.4*x + 11.8 = 29.8$ ; $-2.4*x = 29.8 – 11.8$
$-2.4*x = 18$ ; $x = 18/(-2.4)$ ; x = -7.5

CHECK: $-2.4*(-7.5) + 11.8 = 29.8$ ; 18 + 11.8 = 29.8
29.8 = 29.8 CORRECT!

How do you solve the equation -2.4x+11.8=29.8−2.4x+11.8=29.8-2.4x+11.8=29.8?
