8x+1y+-15 if you are combining variables.
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.
Then x = 6 Therefore; 5x + 3 = 33 First you have to solve the value of X: 8X + 5X + 2X +4X = 114; OR 19x = 114. When you divide both sides of the equation by 19 to solve for X, you find that X = 6. Ergo, 5X + 3 = 30 + 3 = 33; hence, 5X + 3 = 33.
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

To solve for ( y ) in the equation ( 5x = 2y^3 ), you first isolate ( y^3 ) by dividing both sides by 2: ( y^3 = \frac{5x}{2} ). Then, take the cube root of both sides to solve for ( y ): ( y = \sqrt[3]{\frac{5x}{2}} ).
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
5x - 1 = 24 5x - 1 + 1 = 24 + 1 5x = 25 5x/5 = 25/5 x = 5
if you mean 5x -2y = 10 then y = 2.5x -5
5x = 25Divide both sides by 5:x = 5
