-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
2y = 4x + 4y = 2x + 2
If there are no equals you can simplify this by collecting all the x values together and use the addition property of signed numbers. 2x+4x-5x+x=2x; 4+3=7. 2x+7 is the simplified statement.
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
4x
4x=-10 x=-2.5
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
2x + 2x + 146 + 26 = 172 4x + 172 = 172 4x = 0 x = 0
Add 4x + 2x = 6x + 4 = 6x + 4
If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
4x-3+2x-x = 10 Collect the like terms; 5x-3 = 10 5x = 13 x = 13/5
3x - 5x + 4x = -2x +4x = 2x
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
2y = 4x + 4y = 2x + 2
x - 2x + 10 + 4x = 70 Combine like terms: 3x + 10 = 70 Subtract 10 from both sides: 3x = 60 Divided both sides by 3: x = 20
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
