Question

necesito que me ayuden con estos ejercicios​

Answer 1

A. X + 16 = 41
X = 41 - 16
X = 25

B. 9x - 45 + 4x - 16 = 4
13x - 61 = 4
13x = 4 + 61
13x = 65
X = 65/13
X= 5

C. 2x - 3 + x - 35 = 2 - 9x - 4
3x - 38 = -2 - 9x
3x + 9x = -2 + 38
12x = 36
X = 36/12
X = 3

D. 3(2x + 15) - 2(4 + 4x) = 7
6x + 45 - 8 - 8x = 7
-2x + 37 = 7
-2x = 7 - 37
-2x = -30
X = -30/-2
X = 15

E. 2x/3 + 16/3 = -4x/2
2x/3 + 16/3 = -2x
2x/3 + 16/3 = -2x |•3
2x + 16 = -6x
2x + 6x = -16
8x = -16
X = -16/8
X = -2
