First of all add all common factors. In par. (2x) + 15 + (2x) = 180 4x + 15 = 180 Divide 4x and 180 by 4. (4x/4) + 15 = (180/4) x + 15 = 45 Then subtract 15 to 15 and 45. x + (15-15) = (45-15) x = 30 Answer is X = 30.
45 + x + 54 + x 2x + 99
18x + 45 or 9(2x + 5) how is this answer figured?
9(2x + 5)
It depends on what x and y are.
2x-3y-7y+4x-5=6x-10y-5=6*10-10*4-5=60-40-5=60-45=15
66.
17 plus 15 plus 13 equals 45.
It is an algebraic expression.
45 + 9 = 54
45 + 6 = 51
