It is a linear equation in x. It has a solution, which is x = -5

no its not a solution

10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5

Just the one solution.

Since 'x' appears only to the 1st power, this is a linear equation,and there's only one solution.4x + 9 = 25Subtract 9 from each side:4x = 16Divide each side by 4:x = 4

-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.

no its not a solution

10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5

1/2 or .5

4x + 9 = 254x = 25 - 94 x = 16x= 16/4x= 4

If: 4x = x+15 Then: x = 5

4x+9=25 4x+9=25-9 4x/4=1 16/4=4 4x+9=26 4(4)+9=25 16+9=25 The answer is 4
