3.7x + 1.2 = 5.4x - 6.3
If the decimals are problematic, eliminate them by multiplying
both sides of the equation by 10
10(3.7x + 1.2) = 10(5.4x - 6.3)
37x + 12 = 54x - 63
subtract 37x from both sides
37x - 37x + 12 = 54x - 37x - 63
12 = 17x - 63
Add 63 to both sides
12 + 63 = 17x - 63 + 63
75 = 17x
divide both sides by 17
75/17 = 17x/17
5 = x

It's wrong, x = -2.1

To solve the equation 3.7x + 1.2 = 5.4x - 6.3, we need to isolate the variable (x) on one side of the equation. One way to do this is to first subtract 3.7x from both sides, which gives us 1.2 = 1.7x - 6.3. Next, we can add 6.3 to both sides to get 7.5 = 1.7x. Finally, we can divide both sides by 1.7 to get x = -2.1. This means that if we substitute -2.1 for x in the original equation, both sides will be equal.

Calculation path was right but 75/17 = 4.(4117647058823529)
