Y = 2x - 5
3x + 8y + 32 = 56
3x + 8(2x - 5) + 32 = 56
3x + 8(2x) - 8(5) + 32 = 56
3x + 16x - 40 + 32 = 56
19x - 8 = 56
<u> + 8 + 8</u>
<u>19x</u> = <u>64</u>
19 19
x = 3.4
y = 2(3.4) - 5
y = 6.8 - 5
y = 1.8
(x, y) = (3.4, 1.8)
The answer is either b or c

Answer:
£510
Step-by-step explanation:
Simple interest = (principal × rate × time) / 100
Principal = £1700
Rate = 10%
Time = 3 years
Simple interest = (principal × rate × time) / 100
= (1700 × 10 × 3) / 100
= 51,000/100
= 510
Simple interest = £510
