04x + 55 = 9x + 10 55 = 5x + 10 45 = 5x x = 9

It's a simple linear equation in 'x'.You can solve it like this:45 - 5x = 5x + 55Add 5x to each side:45 = 10x + 55Subtract 55 from each side:-10 = 10xDivide each side by 10:-1 = x

5x plus 3 does equal 3 plus 5x; commutative law.

55 = 5x + x + 7Combine the 'x's on the right side:55 = 6x + 7Subtract 7 from each side of the equation:48 = 6xDivide each side by 6 :8 = x

What is the answer to 2x - 5x plus 6.3 equals -14.4?

8x-7 plus 2x equals 6 plus 5x plus 2?

5x + y = 6 so that y = 6 - 5x Also x +2y = 1 so that x + 2*(6-5x) = 1 or x + 12 - 10x = 1 => 9x = 11 or x = 11/9 and then y = 6 - 5x = 6 - 55/9 = -1/9

How do you add 2x plus 3y equals 18 in 5x-y equals 11

The answer to the math problem of 5x plus 12 equals 93-4 is 77/5.

10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5

7-5x=10-(6x+7) 7-5x=-60x-70 +5x +5x 7=-55x-70 +70 +70 77=-55x Divide -55 -1.4 = x

5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8

5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10

30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3

If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3

5x = 4x + 9 x = 9

If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7

If: x+9+5x = 21+2x Then: x = 3

5x - 4x = 13 - 3 ie x = 10

5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3

5x = 3x+1000+0 5x-3x = 1000 2x = 1000 x = 500

5x+3 = -17 5x = -17-3 5x = -20 x = -4

Multiply the bottom equation by -1

If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.

3 + 5x = 38 -> 5x = 35 -> x = 7
