Solve: 3( 4 – X ) = 5( 2X + 3 )?

12-3x=10x+15

-13x=3

x=-3/13

multiply each numbers inside the bracket with the number outside

3(4-x) = 3*4 + 3*(-x) = 12 -3x

5(2x+3) = 5*2x + 5*3 = 10x + 15

12 - 3x = 10x + 15

-3x - 10x = 15 - 12

-13x = 3

x = 3/(-13)

= - 3/13

3( 4 – X ) = 5( 2X + 3 )

=> 3*4 - 3*X = 5*2X +5*3

=> 12 - 3X = 10X + 15

=> -3X - 10X = 15 - 12

=> -13X = 3

=> X = -3/13

the 1st concern you choose to do is do away with all the brackets. 4[x -(3-2x)]+5 = 3(x+11) 4[x-3+2x]+5 = 3x + 33 4x-12+8x+5 = 3x+33 4x+8x-3x = 33-5+12 9x = 40 Then divide the two facets by potential of 9 to remedy for x.

Distribute first

so that becomes

12-3x= 10x+15

Put like terms on the same side, changing the signs

so 12-15=10x+3x

this becomes

-3=13x

x= -13/3

expand the brackets first (open them up)

12-3x=10x+15

12-15=10x+3x

-3=13x

-3/13=x
