Answer:
<em><u>0=x</u></em>
Step-by-step explanation:
First you need to get the variable on one side of the equation
7-x+3=9x+10
+x +x
7+3=10x+10
Now we can combine like terms on the left side of the equation
10=10x+10
Subtract 10 from each side
10=10x+10
-10 -10
0=10x
Divide by 10
0 =10x
/10 /10
<em><u>0=x</u></em>
The answer to this is 1/2 of a meter long.
