Answer: x=7

Step-by-step explanation: First you distribute the 12 to (10-x). That then gives you 15x+120-12x=141. Now you combine like terms. So you do 15x-12x=3x. Your new equation now is 3x+120=141. Subtract 120 from 141 and mark it out. That leaves you with 3x=21. Divide both sides by 3. Your final answer is x=7.

Answer:

[tex]15x+12(10-x)=141[/tex]

[tex]3x+120=141[/tex]

[tex]3x+120-120=141-120[/tex]

[tex]3x=21[/tex]

[tex]\frac{3x}{3}=\frac{21}{3}[/tex]

[tex]x=7[/tex]
