3x + 5 = 20Subtract 5 from each side:3x = 15Divide each side by 3:x = 5
x= 1.67(rnd) 5= -4+3x+4 5- -4= 9 9=3x+4 9-4=5 5=3x x= 1.67(rnd)
x works out as 5/3
fx=3x-5 f=(3x-5)/x f2=(6x-10)/x /=divide
3x-4x=12 that means -x equals 12 so x equals -12
3x + 5 = 20Subtract 5 from each side:3x = 15Divide each side by 3:x = 5
Well if 3x+9=5 x=? Well you minus 9 from the side and then do 5-9 and that equals -4. Then you have to do -4 divided by 3. Which equals -1 so I believe x will equal -1.
3x plus -5 equal 7. so x is 4 so 3times 4 is 12-5 will equal 7.
x= 1.67(rnd) 5= -4+3x+4 5- -4= 9 9=3x+4 9-4=5 5=3x x= 1.67(rnd)
x works out as 5/3
fx=3x-5 f=(3x-5)/x f2=(6x-10)/x /=divide
3x-4x=12 that means -x equals 12 so x equals -12
3x=18 x=18/3 x=6
g (x) = -3x+5 -3x= 5 x= -5/3
If x equals 8, then 3x equals 24. 24-x would equal 16.
If: 3x-7+x = 5 Then: x = 3
3x+5=20 x=5 since 5x3+5=20
