x = 5
If: x + 2/2 + x + 5/7 = 4 Then: x = 8/7
7+(x+5)
7 + 1x + 5 = 12 + x
7
If: 3x-7+x = 5 Then: x = 3
if 3x+5=x+19 then x=7
7 x 1?
x + 2x - x + 7 = 4x - x + 2 Clean this up. 2x + 7 = 3x + 2 Subtract 2x from both sides. 7 = x + 2 Now subtract 2 from both sides. 5 = x ◄ Check 5 + 2(5) - 5 + 7 = 4(5) - 5 + 2 5 + 10 - 5 + 7 = 20 - 5 + 2 15 - 5 + 7 = 15 + 2 10 + 7 = 17 ■
-5
The expression (x+5)(x-7) = x^2 -2x -35
Answer: x = 8/7
