Question

$2x-3=10$$a)2x-3=10 b)4-2x=8 c)6x/2=6 d)2.(x-1)=2+4x$

Answer 1

a)
2x - 3 = 10
2x = 10 + 3
2x = 13
x = $\frac{13}{2}$

b)
4 - 2x = 8
- 2x = 8 - 4
- 2x = 4
x =  $\frac{4}{-2}$
x = - 2

c)
 $\frac{6x}{2}$ = 6
6x = 6 × 2
6x = 12
x =  $\frac{12}{6}$
x = 2

d)
2 × (x - 1) = 2 + 4x
2x - 2 = 2 + 4x
2x - 4x = 2 + 2
- 2x = 4
x =  $\frac{4}{-2}$
x = - 2
