expand the equation
5(x-1)=3x+8
5*x-(5*1)=3x+8
5x-5=3x+8
isolate x and number to opposite sides of the equation
5x-3x-5+5=3x-3x+8+5
simplify
2x=13
x=13/2 or 6.5
double check.
5(6.5-1) = 3(6.5)+8
27.5=27.5

5*x - 5*1 = 3x + 8
5x - 5 = 3x + 8
interchanging the algebras, 5x - 3x = 8 + 5
= 2x = 13 therefore x = 13/2
x = 6.5
thus, in equation 5(x - 1) = 3x + 8, value of x is 6.5.

5(x-1)=3x+8
5x-5=3x+8 (open bracket)
5x-3x=8+5 (like terms together)(sign changes as u take nos on
other side Eg. -5 on left side of equation becomes
+5 on the right)
2x=13
x=13 divided by 2
x=6.5

5(x-1)=3x+8
5*x-(5*1)=3x+8
5x-5=3x+8
5x-3x-5+5=3x-3x+8+5
Solving this Equ.
ie. 2x=13
x=13/2 or 6.5

5x-5=3x+8
5x=3x+13
2x=13
2x divided by 13 and that gives you the answer!
x= 6.5
