10x
2x+52=0 =>2x= -52 =>x= -52/2 =>x= -26
y=-10x-4
10x+5y = 25 5y = -10x+25 y = -2x+5 Therefore: the slope is -2 and the intercept is 5
10x-2x =8x-527
10x 2x divide 2x equals?
x=-1 becaus: 12x+3=2x-7 10x+3=-7 (-2x) 10x=-10 (-3) x=-1 (divided by 10)
2x-3 = 21+10x 2x-10x = 21+3 -8x = 24 x = -3
2x/3 = 8 + 4x2x = 24 + 12x-24 = 10x-2.4 = x
If your question was 2X + 5 =10. X equals what? Then X=2.5
2x-3=10x+21 2x-3-2x=10x+21-2x -3=8x+21 -3-21=8x+21-21 -24=8x -3=x
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
2x 2x
10x - 3 - 2x = 4 7x - 3 = 4 7x = 7 x = 1
10x. 'coz x=? so just add 2 & 8.
2x+5=-91-10x 12x+5=-91 12x=-96 x=-8
