10-3x equals x-2x plus 40?
10 - 3x = x - 2x + 40 10 - 3x = - x + 40 10 - 40 = 3x - x -30 = 2x -15 = x
3x + 9 = 2x + 10?
3x+9=2x+10 3x+9-2x=10 9+x=10 x=1
3x plus 20 and 2x-10 what is the value of x?
If: 3x+20 = 2x-10 Then: x = -30
What is the value of x in 2x plus 50 equals 5x-10?
2X + 50 = 5X - 10 subtract 2X from each side 50 = 3X - 10 add 10 to each side 60 = 3X divide each side by 3 20 = X check 2(20) + 50 = 5(20) - 10 40 + 50 = 100 - 10 90 = 90 checks
X plus 30 equals 3x-50 solve for x?
x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40
6 minus x plus 7minus 3x minus 5 equals negative 2x minus 10?
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
What is the value of x in the equation 3x equals x plus 10?
If 3x = x + 10 then 2x = 10 and x = 5
How do you solve 3x plus 6 equals x-10?
3x+6 = x-10 3x-x = -10-6 2x = -16 x = -8
3x plus 10 equals 14 plus 2x?
3x+10=14+2x so subtract 2x from both sides x+10=14 so x=14-10 so x = 4
2x plus 3x plus 2x plus 3x equals 180?
Ok so 2x + 3x + 2x + 3x = 180.... so combine like terms, 2x + 3x + 2x + 3x is 10x, because 2+3+2+3 is equal to 10, and then so 10x = 180, so divide each side by 10 because the "10" on the left side is multiplying the x, and we want "x" by itself and the opposite of multiplication is division, and 10x/10 is x and 180/10 is 18, so x = 18.
-3x plus 2 equals 2x-8?
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
