you times somthing by 2 then somthing by 5
2*5 = 10
5*2 = 10
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
2 x 2 x 5 x 11
8
x - 5 = 2, we can solve for x by adding 5 to both sides yielding: x = 7
To solve for x: x2 = 5x + 2 x2 - 5x = 2 x2 - 5x + (5/2)2 = 2 + (5/2)2 (x - 5/2)2 = 8/4 + 25/4 x - 5/2 = ± √(33/4) x = (5 ± √33) / 2
2
If you mean: 5+2(x-1) = 12 then the value of x works out as 4.5
x+3y=2 x= -5 y = 1
(x+5)^2 and therefore x = -5
If you mean 2(x+5) + (3*5) then it can be simplified to: 2x+25
X squared - 3x - 10 = 0 (x-5) (x+2) = 0 x - 5 = 0 x + 2 = 0 X= 5 x = -2
x/5 = 2/10 Cross multiply to solve for x. 10x=10. x=1.
