2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
2x+5y=20 Solve for y -2x -2x 5y=20-2x 5 5 5 y=4-2x 5
how do you solve 8+x=x+8
you add 4 to both sides (2x-4 and 16) to cancel out the 4 and get 2x=20. then you divide both sides by 2.
-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
2x 5 -7 = 3
Solve for y: f(-5)=13+2x
2x - 5 = 15 2x = 20 x = 10
2x+5y=20 Solve for y -2x -2x 5y=20-2x 5 5 5 y=4-2x 5
5 - 2x = 16 - 4x ie 4x - 2x = 16 - 5 ie 2x = 11 ie x = 5.5 Check: does 5 - 11 = 16 - 22? Yes, both = -6.
7x - 2x = 80 subtracting like terms, 5x = 80 divide both sides by 5 x = 16
2x - 5 divided by 3 = 2/3x - 5/3
how do you solve 8+x=x+8
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x
you add 4 to both sides (2x-4 and 16) to cancel out the 4 and get 2x=20. then you divide both sides by 2.
