Answer:
11 x 6= 66
11x 4 = 44
So far we have 110
And 11 x 7 will give us 77 so add that by 110 which will give u 187

Answer:
The solution is ( 1/2 , 5)
Step-by-step explanation:
∵ 8x + 7y = 39 ⇒ (1)
∵ 4x - 14y = -68 ⇒ (2)
Multiply (1) by 2
16x + 14y = 78 ⇒ (3)
Add (2) and (3)
∴ 20x = 10 ⇒ x = 10 ÷ 20 = 1/2
∴ x = 1/2
By substitute in (1)
8(1/2) + 7y = 39 ⇒ 7y = 39 - 4 = 35 ⇒ y = 35 ÷ 7 = 5
∴ y = 5
∴ The solution is ( 1/2 , 5)
To check:
8(1/2) + 7(5) = 4 + 35 = 39 = R.H.S
4(1/2) - 14(5) = 2 - 70 = -68 = R.H.S
