Add 4x - 2 to each side: 5x = 5 x = 1
2x + 5 = 7 - 4x ie 2x + 4x = 7 - 5 ie 6x = 2 x = one third.
9x + 5 = 4x + 3 Subtract 4x from both sides: 5x + 5 = 3 Subtract 5 from both sides: 5x = - 2 Divide both sides by 5: x = -2/5 or -0.4
y=(8x).5 + (4x).5 = (2+2sqrt(2))x.5 y'=(1 + sqrt(2))/sqrt(x)
3x+5= 4x-10+10 +103x+15= 4x-3x -3x15=X
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
X equals 2 :)
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
4x + 17 = x + 2 4x - x = 2 - 17 3x = -15 x = -5
4x-14
1/2 or .5
2*2+4x-9=0 4x=9-4 4x=5 x=5/4
4x-y+7=0
Add 4x - 2 to each side: 5x = 5 x = 1
If: 1-2x-5 = 4x+2 Then: -2x-4x = 2-1+5 And: -6x = 6 So: x = -1
z = -4 x-5 y+2
