if you mean 5x -2y = 10 then y = 2.5x -5
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
5x - 4y ≥ -203x - 2y ≤ -8y ≥ -3
There is NO solution, because there is NO equals sign. However, 5x + 3x add to 8x (simplified) Remember in Algebra 5x means '5' multiplied to 'x' and '3' multiplied to 'x'. The multiplication sign is never shown in algebra.
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
If you mean: 2x+y = -6 and 5x-3 = 7 then the solutions are x = -1 and y = -4
5x-19 = 16 5x = 16+19 5x = 35 x = 7
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5

5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x - 1 = 24 5x - 1 + 1 = 24 + 1 5x = 25 5x/5 = 25/5 x = 5
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
5x = 25Divide both sides by 5:x = 5
if you mean 5x -2y = 10 then y = 2.5x -5
There's nothing to solve, it's simply an expression.
