Step-by-step explanation:

Answer 2

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

(4)

(4)

(I'm not soo sure about this one)

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

the number of shirt they can buy is 5 or 5.4
