Answer 1

2.

(i) 13x–8=x+4

==>13x–x=4+8

==>12x=12

==>x=12÷12

==>x=1

(v) 5x–3=3x–5

==>5x–3x=–5+3

==>2x=–2

==>x=–2÷2

==>x=–1

(vi) 7+5x=15+3x

==>5x–3x=15–7

==>2x=8

==>x=8÷2

==>x=4

3.

(i) 2(x–2)–3(x–3)=5(x–5)

==>2x–4–3x+9=5x–25

==>–x+5=5x–25

==>5+25=5x+x

==>6x=30

==>x=30÷6

==>x=5

(ii) 5(3x+4)–8(6x–7)=9x–8

==>15x+20–48x+56=9x–8

==>–33x+76=9x–8

==>76+8=9x+33x

==>42x=84

==>x=84÷42
