18x + 45 or 9(2x + 5) how is this answer figured?
9(2x + 5)
2x-3 = 17 2x = 17+3 2x = 20 x = 10
10 - 3x = x - 2x + 40 10 - 3x = - x + 40 10 - 40 = 3x - x -30 = 2x -15 = x
2X - 5Y = 10 subtract 2X from each side - 5Y = - 2X + 10 divide each side by - 5 Y = 2/5X - 2 slope(m) = 2/5
This website isn't equipped to reproduce most mathematical symbols in the questions. I'll see if I can translate. 2x + 3(x - 10) = 45 2x + 3x - 30 = 45 5x - 30 = 45 5x = 75 x = 15 Check it. 2(15) + 3(15 - 10) = 45 30 + 15 = 45 It checks.
It is an algebraic expression.
If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
4 - 2x = 10 -2x = 10-4 -2x = 6 -x = 3 x = -3
2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
Any pair of numbers where the 'y' is 5 more than the 'x'. There are an infinite number of suitable pairs. 2y-2x=10 2y-2x+2x=10+2x 2y=2x+10 divide both side by 2. y=x+5
2x-2 = 10 2x= 10+2 2x=12 x= 12/2 x=6
2x-3y-7y+4x-5=6x-10y-5=6*10-10*4-5=60-40-5=60-45=15
2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9
3x+9=2x+10 3x+9-2x=10 9+x=10 x=1
