Answer 1

O)3x+5+2×+6=x+27

5 + 6 -27 = x -2x - 3x

-16 = -4x (-1)

16 = 4x

x = 16/4

x = 4

P)10x-5=3x+30

10x - 3x = 30 + 5

7x = 35

x = 35/7

x = 5

Q)7y-10=y+50

7y - y = 50 + 10

6y = 60

y = 60/6

y = 10

R)5×-91=4×-77

5x - 4x = -77 + 91

x = 14

S)3x+3+4x-6=5x-5+8

7x - 5x = -5 + 8 +6 - 3

2x = 6

x = 6/2

x = 3

T)4x+14+9x-5=12x-15-1

13x - 12x = -16 + 5 - 14

x = -15
