Step-by-step explanation (Question 1):
Step 1: (Question 1): Subtract x from both sides.
5x+3=x+13
5x+3−x=x+13−x
4x+3=13
Step 2: (Question 1): Subtract 3 from both sides.
4x+3−3=13−3
4x=10
Step 3: (Question 1): Divide both sides by 4.
4x/4 = 10/4
FIRST ANSWER: x = 5/2
Step-by-step explanation (Question 2):
Step 1: (Question 2): Multiply by LCM
15x^2 - 6 = x
Step 2: (Question 2): Solve 15x^2
15x^2 - 6 = x:
x = 2/3
x = -3/5
Step 3: (Question 2): Solve
ANSWER: x=0.666667 or x=−0.6
