Question

find all questions by transposition method (i) 2(z+1)=3(z+4) (ii) x/5+×/3=10 (iii) 2m+4-3m=8(m-1) (IV) 5(y+2)-4(y-1)-6

Answer 1

1) 2(z+1)=3(z+4)
2z+2=3z+12
2z-3z=12-2
-z=10
z=-10

2)x/5+x/3=10
3x+5x/15=10
8x=150
x=150/8

3)2m+4-3m=8(m-1)
4-m=8m-8
-m-8m=-8-4
-9m=-12
3m=4
m=4/3

4)5(y+2)-4(y-1)-6=0
5y+10-4y+4-6=0
y+8=0
y=-8
