Answer:
39
Step-by-step explanation:
you need to work backwards
86-2-6=78
therefore, 78 = 2y
y = 2y/2, so 78/2 = 39
Answer:
The value 39 will make the equation true
Step-by-step explanation:
Y + 2 + 6 + Y = 86
Y + Y + 2 + 6 = 86
2Y + 8 = 86
2Y = 86 - 8
2Y = 78
Y = 78 ÷ 2
Y = 39
Thus, The value 39 will make the equation true
Y + 2 + 6 + Y = 86
39 + 2 + 6 + 39 = 86
86 = 86
Hence, L.H.S = R.H.S
