What does x equal in this equation- 5x plus 2 equals x plus 12?
5x + 2 = x + 12 5x - x = 12 - 2 4x = 10 x = 10/4 x = 5/2 or 2.5
What is the answer to 5-4x equals 12-2x?
5-4x=12-2x isolate your x's on one side 5=12-2x+4x 5-12=-2x+4x simplify -7=2x divide by 2 x=-7/2, or x=-3.5

X plus 2 plus 2x equals x plus 12?
so 3x + 2 = x + 12 ie 2x = 10 x =5
7x plus 12 equals 5x plus 2?
x = -5
What does x equal in this equation- 5x plus 2 equals x plus 12?
5x + 2 = x + 12 5x - x = 12 - 2 4x = 10 x = 10/4 x = 5/2 or 2.5
Use the substitution method to solve the system of equations x plus 2y equals 12 and y equals x plus 3?
x+2(x+3) = 12 x+2x+6 = 12 x+2x = 12-6 3x = 6 x = 2 and y = 5
What is the answer to 5-4x equals 12-2x?
5-4x=12-2x isolate your x's on one side 5=12-2x+4x 5-12=-2x+4x simplify -7=2x divide by 2 x=-7/2, or x=-3.5
What is the value of 5x -3y when x equals -2 and y equals -4?
5(-2)+(-3)(-4) =-(10)+12 =2
