Solve the equation: 7(x + 8) = 49​

-1

Step-by-step explanation:

1.)Reorder the terms:

7(8 + x) = 49

(8 * 7 + x * 7) = 49

(56 + 7x) = 49

2.)Solving

56 + 7x = 49

3.)Solving for variable 'x'.

4.)Move all terms containing x to the left, all other terms to the right.

5.)Add '-56' to each side of the equation.

56 + -56 + 7x = 49 + -56

6.)Combine like terms: 56 + -56 = 0

0 + 7x = 49 + -56

7x = 49 + -56

7.)Combine like terms: 49 + -56 = -7

7x = -7

8.)Divide each side by '7'.

x = -1

9.)Simplifying

x = -1
