147º
Step-by-step explanation:
180-33=147
5x + 1 = 5x + n
n - any real number except 1
Examples:
n = 2
5x + 1 = 5x + 2 <em>subtract 5x from both sides</em>
1 = 2 FALSE -> NO SOLUTION
n = 0
5x + 1 = 5x + 0 <em>subtract 5x from both sdies</em>
1 = 0 FALSE -> NO SOLUTION
n = -4
5x + 1 = 5x + (-4) <em>subtract 5x from both sides</em>
1 = -4 FALSE -> NO SOLUTION
