Answer:

x=1/3

Step-by-step explanation:

5=4+3x

5=3x+4 (Simplify both sides of the equation)

3x+4=5 (Flip the equation)

3x+4−4=5−4 (Subtract 4 from both sides)

3x=1

3x/3=1/3 (Divide both sides by 3)

x=1/3

Answer: -15

Cross multiplication

5(x+3)=4x

5x+15=4x

-5x. -5x

15 = -1x

/-1. /-1 = -15=x
