An number with a x after mean multiply, so it would be 4x12=48
If: 4x-4 = 12 Then: x = 4
If: 4x+(-12) = 8 then 4x = 20 and x = 5
4x+3y = 12 3y = -4x+12 y = -4/3x+4
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3
A = 4x + 12 = 4x + 4 × 3 = 4(x + 3)
If: 4x-4 = 12 Then: x = 4
If: 4x+(-12) = 8 then 4x = 20 and x = 5
There is no equation in the question: only an expression. An expression has no answer.
4X - 1 = 9 Is an equation. 4X - 1 = 9 4X = 10 X = 5/2 =====
It is: y = -4x+12
48
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
If: 4x-4 = 12 Then: x = 4
2x - 3y -7y + 4x - 5 = 6x - 10y - 5 and (6 x 10) - (10 x 4 ) - 5 = 60 - 40 - 5 = 15
4x-5=7 4x=12 x=3
4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
