-11=18+s/5
To find the sum of 2xx and 5, we first need to determine the value of xx. Since 18 is the sum of 2xx and 5, we can set up the equation 2xx + 5 = 18. By subtracting 5 from both sides, we get 2xx = 13. Dividing by 2 on both sides gives us xx = 6.5. Therefore, 18 is the sum of 2(6.5) and 5.
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.

it is 3x3 not that hard
Points: (13, 19) and (23, 17) Midpoint: (18, 18) Slope: -1/5 Perpendicular slope: 5 Perpendicular equation: y-18 = 5(x-18) => y = 5x-72
x+5=18 When you move 5 to the other side, you get x=13.
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
Points: (20, 18) and (35, 6) Slope: -4/5 Equation: y = -4/5x+34
If you simplify this equation, then you get -3x=18. Divide both sides by -3 and you get x=-6.
x2 + 10x = 18 x2 + 2(5)x - 18 = 0 x2 + 2(5)x + 25 = 18 + 25 (x + 5) 2 = 43 x + 5 = 430.5 x=6.56(3sf)-5
5(2X) = 18 take natural log each side ln[5(2X)] = ln(18) now, as a logarithmic operation the exponent can come down in front of the log sign 2X ln(5) = ln(18) divide thus 2X = ln(18)/ln(5) [ not ln(18/5)!!!! ] 2X = 1.795888947 divide by 2 X = 0.8979444735 -------------------------------check in original equation 5(2*0.8979444735) = 18 18 = 18 -------------checks
18 = X + 5/2 multiply through by 2 36 = 2X + 5 subtract 5 from each side 31 = 2X divide both sides integers by 2 31/2 = X check in original equation 18 = 31/2 + 5/2 18 = 36/2 18 = 18 checks
