Example Problems to Pre Algebra Help Free Website:
Example 1:
Solve the equation for x, 55x + 57 = 88
Solution:
55x + 57 = 88 (add -57 on both sides)
55x + 57 57 = 88 57
55x = 31 (divide both terms by 55)
'(55x)/55' = '31/55'
x = .56
Example 2:
Solve the equation for x, 5(5x - 58) = 59.
Solution:
5(5x - 58) = 59 (multiply 5 within the parenthesis)
(5 'xx' 5x) (5 'xx' 58) = 59
25x 290 = 59 (add both sides by 290)
25x - 290 + 290 = 59 + 290
25x = 349 (divide both side by 25)
'(25x)/ 25' = '349/25'
x = 13.96
Example 3:
Solve the equation for x, '(5x-55)/5' = 57 .
Solution:
'(5x -55)/5' = 57 (multiply both sides by 5)
'(5x-55)/5' 'xx' 5= 57 5
5x 55= 275 (add both sides by 55)
5x 55+ 55= 275 + 55
5x = 330 (divide both sides by 5)
'(5x)/5' = '330/5'
x = 66
Example 5:
Solve the equation 5x - 55 = 57 for x.
Solution:
5x - 55 = 57 (add both sides by 55)
5x 55 + 55 = 57 + 55
5x = 112 (add both sides by 5)
'(5x)/5' = '112/5'
x = 22.4
Example 5:
Solve the equation 5x 56 = 59 for x.
Solution:
5x 56 = 59 (add both sides by 56)
5x 56 + 56 = 59 + 56
5x = 115 (divide both sides by 5)
'(5x)/5' = '115/5'
x = 23
