Step-by-step explanation:
(1)
1 x = 12
3
multiply both sides by the 3
3 × 1 x = 12 × 3
3
x = 36
(2)
3x + 3 = 21
( group like terms)
3x = 21 - 3
3x = 18
( divide both sides by 3)
3x = 18
3 3
x = 6
(3)
9.95 + 0.30( 35 )
=9.95 + 10.5
=20.45

equation = 6x + 27 = x
11
solution
( multiply both sides by 11)
= (6x + 27) ×11 = x × 11
11
= 6x + 27 = 11x
( grouping like term)
27 = 11x - 6x
27 = 5x
(divide both sides by 5)
27 = 5x
5 5
x = 5.4
