Answer 1

3x+4(x+3)=7
3×+4×+12=7
7×+12=7
7×=-5
×=-5/7

Answer 2

Answer:

x = $\frac{-5}{7}$

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.

$\frac{7x}{7} = \frac{-5}{7}$
