Answer:
x=12
Step-by-step explanation:
f(x)=16x-30 and g(x)=14x-6
(f-g)(x)=0
f(x)=16x-30 -(14x-6)
Distribute
= 16x -30 -14x +6
Combine like terms
= 16x-14x -30+6
2x-24
Set this equal to zero
2x-24 =0
Add 24 to each side
2x-24 +24=0+24
2x=24
Divide by 2
2x/2 =24/2
x = 12

Step-by-step explanation:
3 balloons + 2 cakes = £19
=> 9 balloons + 6 cakes = £57 (multiply by 3)
9 balloons + 6 cakes = £57
- (9 balloons + 3 cakes = £42)
=> 3 cakes = £15, 1 cake = £5.
Therefore 3 balloons + 2(£5) = £19,
3 balloons = £9, 1 balloon = £3.
Hence each balloon is £3 and each cake is £5.
