Question

(3 + 5) * 2Y = (5 * 8) - (2 * 4)​

Answer 1

Answer:

Y = 2

Step-by-step explanation:

Solve for Y:

(3 + 5)×2 Y = 5×8 - 2×4

3 + 5 = 8:

8×2 Y = 5×8 - 2×4

5×8 = 40:

8×2 Y = 40 - 2×4

-2×4 = -8:

8×2 Y = -8 + 40

8×2 = 16:

16 Y = 40 - 8

40 - 8 = 32:

16 Y = 32

Divide both sides of 16 Y = 32 by 16:

(16 Y)/16 = 32/16

16/16 = 1:

Y = 32/16

The gcd of 32 and 16 is 16, so 32/16 = (16×2)/(16×1) = 16/16×2 = 2:

Answer: Y = 2
