  • Nnesha
did you solve the equation ??
anonymous
  • anonymous
It was a guess lol @Nnesha
Nnesha
  • Nnesha
mhm not good.......
Nnesha
  • Nnesha
\[\huge\rm 5x+\color{reD}{3}(x-1)=10x-2x -3\] solve this equation distribute parentheses by 3
anonymous
  • anonymous
Give me some time lol
anonymous
  • anonymous
hmm
Nnesha
  • Nnesha
okay :-)
Nnesha
  • Nnesha
multiply everything which is inside the parentheses by 3 3(x-1)
anonymous
  • anonymous
Algebra is not by best subject ;)
Nnesha
  • Nnesha
it will if you practice
anonymous
  • anonymous
so (x-3) ?
Nnesha
  • Nnesha
nope |dw:1433343032825:dw| 3 times x = ?
anonymous
  • anonymous
3?
anonymous
  • anonymous
so (3-3)
Nnesha
  • Nnesha
x is same as 1x so multiply coefficient 3 times 1x (3 times 1)x = 3x
anonymous
  • anonymous
so (3x-3)? :/
Nnesha
  • Nnesha
\[\huge\rm 5x+\color{reD}{3x-3} =10x-2x -3\] now combine like terms both side left and right
Nnesha
  • Nnesha
yep that's right now we can remove de parentheses
anonymous
  • anonymous
now what
anonymous
  • anonymous
:)
Nnesha
  • Nnesha
combine like terms :-)
anonymous
  • anonymous
Hmm, what does that mean? :(
anonymous
  • anonymous
Isn't it like subtract the two numbers
anonymous
  • anonymous
Or add*
Nnesha
  • Nnesha
yep subtract or add coefficient of same variables for example 2y and 3y are like terms so we can add them = 5y 3 +9 are like terms = 12
anonymous
  • anonymous
So x - 6?
Nnesha
  • Nnesha
L.h.s 5x+3x -3 combine like terms
anonymous
  • anonymous
So -3 plus 3 = 0, then 3 minus 5 = 1?
Nnesha
  • Nnesha
\[\huge\rm \color{red}{5x+3x }-3 \]here 5x and 3x are like terms combine them 5x+3x= ?
anonymous
  • anonymous
8x?
Nnesha
  • Nnesha
yep right \[\huge\rm \color{reD}{8x-3} =10x-2x -3\] now combine like terms right side 10x-2x -3 = ?
anonymous
  • anonymous
12x -3?
Nnesha
  • Nnesha
mhm 10x minus 2x = ? subtract
anonymous
  • anonymous
8x
Nnesha
  • Nnesha
yep right \[\huge\rm 8x -3 = 8x-3\] both sides are same right ?
anonymous
  • anonymous
yes
Nnesha
  • Nnesha
if both sides are not equal then 0 = 3 no solution if both sides are equal 7 = 7 infinitely many solution
anonymous
  • anonymous
Thank you so much!
Nnesha
  • Nnesha
np :-)
