Question

Poderiam me ajudar com essas equações?

14R + 24 = 10R + 2R + 30

25 - 3A + 2 = 2A + 17

X - 4 + 5X = 4X + 8

-3X + 8 = 5X + 16

9 - 3X = -5 + 4X

5+ - 6 = 3 - 4+

Answer 1

14R - 12R = 30 - 24
2R = 6
R = 6/2
R = 3

-3A - 2A = 17 - 27
-5A = -10
A = -10/-5
A = 2

X + 5X - 4X = 8 + 4
2X = 12
X = 12/2
X = 6

-3X - 5X = 16 - 8
-8X = 8
X = 8/-8
X = 1

-3X - 4X = -5 - 9
-7X = -14
X = -14/-7
X = 2

5+ + 4+ = 6 + 3
9+ = 9
+ = 9/9
+ = 1
