Answer :
Answer:
x = [tex]\frac{-5}{7}[/tex]
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x+4(x+3)=7
3x+(4)(x)+(4)(3)=7(Distribute)
3x+4x+12=7
(3x+4x)+(12)=7(Combine Like Terms)
7x+12=7
7x+12=7
Step 2: Subtract 12 from both sides.
7x+12−12=7−12
7x=−5
Step 3: Divide both sides by 7.
[tex]\frac{7x}{7} = \frac{-5}{7}[/tex]
