5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
The value of x in the equation 5x+6=30 is 4.8.Check5x+6=305(4.8)+6=3024+6=3030=30
2x plus 5x simplified is 7x.

30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
4x+12-5x-30=-x-18
= (5x - 30) + (3 - 7) = 5x - 30 - 4 = 5x - 34
39 = 5x + 9 5x = 39 - 9 5x = 30 x = 30 / 5 x = 6
-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
If you mean: -5x+6y = 30 then y = 5/6x+5 as a straight line equation
5x+2y = 30 2y = -5x+30 y = -2.5x+15 Therfore the slope is 2.5 and y the intercept is 15.
8x + 30 = 5xSubtract 30 from each side:8x = 5x - 30Subtract 5x from each side:3x = -30Divide each side by 10:x = -10
