Answer 1

Correct ;)

Answer 2

If we have the equation 7x = 15 + 6, we can solve it using substitution by isolating x on one side of the equation.

First, we start by subtracting 6 from both sides of the equation:
7x - 6 = 15

Next, we can divide both sides of the equation by 7 to solve for x:
(7x - 6)/7 = 15/7
x - 6/7 = 15/7

Finally, we can simplify the equation to get the value of x:
x = (15/7) + (6/7)
x = 21/7
x = 3

Therefore, the solution to the equation 7x = 15 + 6 using substitution is x = 3.
