5 - 4 + 7x + 1 = 7x + (5 - 4 + 1) = 7x + 2


NO SOLUTIONS:

<em>5 - 4 + 7x + 1 = 7x + a    </em><em>(a - any real number, except 2)</em>


ONE SOLUTION:

<em>5 - 4 + 7x + 1 = bx + c     </em><em>(b - any real number, except 7, c - any real number)</em>


INFINITELY MANY SOLUTIONS:

<em>5 - 4 + 7x + 1 = 7x + 2</em>


Examples:

2x + 3 = 2x + 5     <em>subtract 2x from both sides</em>

3 = 5    FALSE      <em>(NO SOLUTIONS)</em>


2x + 3 = x - 4      <em>subtract x from both sides</em>

x + 3 = -4       <em>subtract 3 from both sides</em>

x = -7          (<em>ONE SOLUTION)</em>


2x + 3 = 2x + 3      <em>subtract 2x from both sides</em>

3 = 3     TRUE      <em>(INFINITELY MANY SOLUTIONS)</em>

The sum of two numbers is 17, and their difference is 29. What are the two numbers?
serious [3.7K]
X + y = 17
x - y = 29

x = 17 - y
x - y = 29

x = 17 - y
17 - y - y = 29

x = 17 - y
17 - 2y = 29

x = 17 - y 
- 2y = 29 - 17

x = 17 - y
-2y = 12

x = 17 - y 
y = -6

x = 17 - (-6)
y = -6

x = 17 + 6
y = -6

x = 23
y = -6
