5x-2=13 +2 +2 5x=15 x=3
Without an equality sign it is not an equation but if you mean: 5x=2 then x=2/5 or 0.4
In the equation 43X +2=5X, X=-1/19.
yes. check: 3x-6=5x-10 2x=4. X=2. yay!
If you mean: x2+5x+6 = 0 then the solutions are x = -3 and x = -2
Let the number be x4x-3(x+2)=54x-3x-6=5x=11
-5x + 7y = 11 (1) -5x + 3y = 19 (2) Subtract (2) from (1) 4y = -8 divide both sides by 4 y = -2 (the y-coordinate of the solution point) Replace -2 for y at one of the given equations, let's say at (2). -5x +3(-2) = 19 -5x - 6 = 19 add 6 to both sides -5x = 25 divide both sides by -5 x = -5 (the x-coordinate of the solution point) Thus, the solution point is (-2, -5).

This cannot be solved. It needs 2 equations to solve for 2 unknowns.

I could be missing something here, but I'm pretty sure the two 5x's cancel out and you would get 2=0, which is not true. so the answer would be no solution. Hope that helps!
Five times the sum of 6 and a number is 2 more than the numberWrite the equation5(6 + x) - 2 = x30 + 5x - 2 = x5x + 28 = x4x = -28x = -7Check: 5 (6 + (-7)) - 2 = -75(-1) - 2 = -7
(4x - 8) + 2x = 6 + x4x - 8 + 2x = 6 + x6x - 8 = 6 + xSubtract x from each side:5x - 8 = 6Add 8 to each side:5x = 14Divide each side by 5:x = 14/5 = 2-4/5 = 2.8
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
