4x+9=25 4x=16 x=4
10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
4x + 9 = 254x = 25 - 94 x = 16x= 16/4x= 4
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
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
9x+3-25 = 4x-2 5x = 20 x = 4
Subtract 4x from each side: 4x + 9 = 25Subtract 9 from each side: 4x = 16Divide each side by 4: x = 4

It is a linear equation in x. It has a solution, which is x = -5
4x-14
4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27
x+x+1+x+2+x+25=845 4x+28=845 4x=817 x=204.25
