Answer:
Step-by-step explanation:
(a) y+8= -3
y= -3-8(by transposing 8 to rhs)
y=-11
(b) 2q+4=16
2q=16-4
2q=12
q=12÷2
q=6
(c) 3a= -9
a= -9÷3
a=-3
(d) 5(x+2) =6
5x+10=6
5x=6-10
5x=-4
x=-4/5
(e) 7+5a=5
5a=5-7
5a=-2
a=-2/5
(f) 2(5x+5) =20
10x+10=20
10x=20-10
10x=10
x=10/10
x=1
(g) ¾x=6
x=6×4/3
x=2×4
x=8
(h) 13p-7=1
13p=1+7
13p=8
p=8/13
(I) 2y+6+10/9=14
2y+6+10=14×9
2y+6+10=126
2y+16=126
2y=126-16
2y=110
y=110/2=55
(j) 8x/3+4=12
8x=12-4
8x=8
x=8/8
x=1
(k) x/5=3
x=3×5
x=15
(l) 4y-7=7
4y=7+7
4y=14
y=14/4
y=7/2
