Yes. This demonstrates the Commutative Property of addition.
38*4 + 3 + 7 - 3x = 162 - 3x
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
3x + 7 = 3(-3) + 7= -9 + 7= -2
y = 2x^(2) + 3x + 7 dy/dx = 2(2)x^(2-1) + 3(1)x^(1-1) + 7(0)x^(0-1) dy/dx 4x^(1) + 3x^(0) + 0 dy/dx = 4x + 3(1) dy/dx = 4x + 3 The answer!!!!! I have made a bit of 'heavy weather' of this but only to try and show you how it works out.
4x - 3x + 7 = -3 x = -3 - 7 = -10
3x+7=37 -7 -7 3x=30 /3 /3 x=10
eq: 3x+5=7 =3x=7-5 =3x=2 =x=2/3
x+7=3x+3 4=2x 4/2=2 x=2
3x + 4 + 9 - 6 = 3x + 7----If you ment 3x + 4 + 9 = 6=> 3x + 13 = 6{subtract 13 from both sides}=> 3x = -7{divde by 3 on both sides}=> x= -7/3
-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
7x = 3 x = 3/7
