Answer:
x=3.4

Simplify both sides of the equation


10x+-4.5+3x=12x+-1.1


(10x+3x)+(-4.5)=12x-1.1(Combine Like Terms)


13x+-4.5=12x-1.1

Subtract 12x from both sides


13x-4.5-12x=12x-1.1-12x\\x-4.5=-1.1

Add 4.5 to both sides


x-4.5+4.5=-1.1+4.5\\x=3.4

Answer:


x = 3.4

Explanation:


10x -4.5 + 3x = 12x - 1.1 \\ 10x + 3x - 12x = 4.5 - 1.1 \\ 13x - 12x = 4.5 - 1.1 \\ x = 3.4
