-4x +5x +4 =7 x + 4 = 7 x = 3
-7
8x - 4 = -7 + 5x8x - 5x - 4 = -7 + 5x - 5x subtract 5x from both sides3x - 4 + 4 = -7 + 4 add 4 to both sides3x = -3x = -3/3 = -1
(3, -4)
5x + 13
8x-4 = -7+5x 8x-5x = -7+4 3x = -3 x = -1
-4x +5x +4 =7 x + 4 = 7 x = 3

8x - 4 = -7 + 5x8x - 5x - 4 = -7 + 5x - 5x subtract 5x from both sides3x - 4 + 4 = -7 + 4 add 4 to both sides3x = -3x = -3/3 = -1

5x plus 4
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
8x-7 plus 2x equals 6 plus 5x plus 2?
8x = 32 so x = 4
5x + 13
-5x + 7 = 27Add (5x - 27) to each side ==> -20 = 5xDivide each side by 5 ==> -4 = x
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
