2x + 3(x -4) = 18
1042, or x=2605
2x - 5 = 15 2x = 20 x = 10
2x+5 = 62 and 3x-y = 23.3 x = 28.5 and y = 62.2 Solve the first equation and then substitute the value of x into the second equation to find the value of y.
The solution to the equation 2x plus 2 is 2(x + 1).
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
To solve the equation f(x) = 2x-5, set f(x) equal to zero and solve for x. In this case, you have 2x-5 = 0. Add 5 to both sides of the equation to isolate the x term, giving you 2x = 5. Finally, divide both sides by 2 to solve for x, which gives x = 5/2 or x = 2.5.
To solve this equation we have to isolate and solve for x. So: 2x-6= x+5 +6 +6 2x = x+11 -x -x x = 11 So x=11.
This is already the equation. Now you just have to solve it. x=5.
2x+4-x = 4x-5 2x-x-4x = -5-4 -3x = -9 x = 3
You add or subtract some quantity on both sides of the equation, so that you only have "x" on one side of the equation. Example: 4x + 3 = 2x - 5 Subtract 2x on each side, this leaves you: 4x - 2x + 3 = 2x - 2x -5 2x + 3 = -5
1 + 3x - x = x - 4 + 2x 1 + 4 = x + 2x - 3x + x 5 = x
Y=0.5 and X=1
-2x+5 x=-3 --original equation-2(-3)+5 --use substitution property6+5 --solve.11 --final answer is 11.
3x-2 = 2x+3 3x-2x = 3+2 x = 5
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x
2x + 3(x -4) = 18
