Question

Help solving this math

Answer 1

Answer:

(1) 9n = 56

        n = 6

(2) 10 + 4y = 38

        y = 7

(3) 3x + 8x = 55

        x = 5

(4) 6m + 20 = 8

        m= -2

(5) 17 - 3a = 23

        a = -2

(6) 10x + 4 = 6x + 16

        x = 3

(7) 4(x - 2) + x = 17

        x = 5

(8) 2(x + 3) + 3x = x + 22

        x = 4

(9) D. 10

(10) -2(3x - 2.4) = 3(3x - 2.4)

       im not sure about this equation

Hope this helps
