IN equation form, when the number is x: 3x = 6 + 4x 3x - 4x = 6 -x = 6
When -25=4x+7 Then -25-7 = 4x And -32 = 4x So the number is -32/4 = -8
4x - 11 = 49 4x = 60 x = 15
Let the unknown number be x: 4x+12 = 4 4x = 4-12 4x = -8 Divide both sides of the equation by 4 to find the vlue of x: x = -2
4x - 15 = 5x - 10 5x = 4x - 5 x = -5
