Simplify both sides of the equation
3(x-4)+12(x-9)=4x+13
Distribute
(3)(x)+(3)(-4)+(12)(x)+(12)(-9)=4x+13
3x+-12+12x+-108=4x+13
Combine like terms
15x+-120=4x+13
15x-120=4x+13
Subtract 4 from both sides
15x-120-4x=4x+13-4x
11x-120=13
Add 120 to both sides
11x-120+120=13+120
11x=133
Divide both sides by 11
11x/11=133/11
x=133/11
or x= 12 1/11
I hope that's help !
Answer:
Step-by-step explanation:
The answer is 12.35
