Question

10x-4.5+3x=12x-1.1 what is the solution for x in the equation

Answer 1

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 2

Answer:

$x = 3.4$

Step-by-step explanation:

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