2x + 5 + 3x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4
It is, as stated, x2 - 5x + 25/4 = 0
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
How to solve: 5x+2=27 5x=25 (Subtract 2 from each side) x=25/5=5 (Divide each side by 5) So, x=5
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
5x+25=10 5x+25-25=10-25 5x=-15 5x/5=-15/5 x=-3
(2,7)
4x + 5 + x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4
9x+3-25 = 4x-2 5x = 20 x = 4
-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x+3 = -17 5x = -17-3 5x = -20 x = -4
2x + 5 + 3x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4
