5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
Given: 5X - 18 = 4X + 4; subtracting 4X from each side: X - 18 = 4; adding 18 to each side, X = 22
x= -11
4x - 10 + 5x = 719x = 81x = 9
6 + x - 10x = 11 - 4x 6 - 9x = 11 - 4x add 9x to both sides: 6 = 11 + 5x subtract 11 from both sides: -5 = 5x divide both sides by 5: -1 = x
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
Given: 5X - 18 = 4X + 4; subtracting 4X from each side: X - 18 = 4; adding 18 to each side, X = 22
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
x= -11
How do you add 2x plus 3y equals 18 in 5x-y equals 11
4x-7=5x-2 x=-5
5x = 4x + 9 x = 9
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
4x - 10 + 5x = 719x = 81x = 9
6 + x - 10x = 11 - 4x 6 - 9x = 11 - 4x add 9x to both sides: 6 = 11 + 5x subtract 11 from both sides: -5 = 5x divide both sides by 5: -1 = x
5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
5x + 51 = 9x + 11 Becomes 40 = 4x So x = 10
