I am not sure what to round it to because that part of the question was cut off in the picture, but the answer is [tex] -\frac{1}{7} [/tex] or [tex]-0.1428...[/tex]
Here's the math:
[tex]6(4x+5)=3(x+8)+3[/tex]
Step 1.) Distribute the 6 across it's parenthesis and the 3 across its parenthesis
[tex]24x+30=3x+24+3[/tex]
Step 2.) Combine like terms
[tex]24x+30=3x+27[/tex]
Step 3.) Subtract 3x from both sides
[tex]21x+30=+27[/tex]
Step 4.) Subtract 30 from both sides
[tex]21x=-3[/tex]
Step 5.) Divide both sides by 21
[tex]x= -\frac{3}{21} [/tex]
Step 6.) Simplify the fraction with the GCF of 3
[tex]x= -\frac{1}{7} [/tex]
It is asking for a decimal though, so to find that, we divide -1 ÷ 7 = -0.142857
Thank you for your question! I hope this helped! Have an amazing day! :D
