it means that x should equal 10. x + x = 20. x = 10
20 as 10 x 0 = 0 so is just 10 + 10 = 20
(20 * x) + 3 = 5 20 * x = 2 x = 1/10
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
it means that x should equal 10. x + x = 20. x = 10
20 as 10 x 0 = 0 so is just 10 + 10 = 20
x = 10
The solution is:- x = 0 and y = 5
(20 * x) + 3 = 5 20 * x = 2 x = 1/10
1.3 x 10-20
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
4x =20x=20/4x=5
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
x equals 19
