Question

Find a value of x that is a solution to 5(x – 3) = x + 13.

Answer 1

Answer:

x=7

Step-by-step explanation:

$5(x-3)=x+13\\5x-15=x+13\\Subtract x from both sides \\4x-15=13\\Add 15 to both sides\\4x= 28\\Divide both sides by 4\\x=7$

Now check your answer

$5(7-3)=7+13\\35-15=20\\20=20$

Answer 2

Answer:

x = 7

Step-by-step explanation:

$5(x-3)=x+13$

distribute

$5x-15= x+13$

combine like terms

$5x-x = 13 + 15$

$4x=28$

x = 7
