X + 4y = 17

8x - 7y = 58

Problem 1 Answer: x = 17 + - 4y

Show Work:

1) Simplifying

x + 4y = 17

2) Solving

x + 4y = 17

3) Solving for variable 'x'.

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

5) Add '-4y' to each side of the equation.

x + 4y + - 4y = 17 + - 4y

6) Combine like terms: 4y + - 4y = 0

x + 0 = 17 + - 4y

x = 17 + - 4y

7) Simplifying

x = 17 + - 4y

Problem 2 Answer: x = 7/8y + 29/4

Step 1: Add 7y to both sides.

8x-7y+7y=58+7y

8x=7y+58

Step 2: Divide both sides by 8.

8x/8 = 7y+58/8

x = 7/8y + 24/9
