U can subtract 18 from each side of the equation.
6x-4 = 18 6x = 18+4 6x = 22 x = 22/6 = 3 and 2/3
D - 9 = 9 d = 9 + 9 d = 18
b + 7 = 18 subtract 7 from each side b + 7 - 7 = 18 - 7 b = 11 ----------------check in original equation 11 + 7 = 18 18 = 18 --------------checks
To find the x-intercept for 5x - 4y = 18, plug in a 0 for the y value and solve for x. 5x - 4(0) = 18 5x = 18 x = 18/5 or 3.6 The line will hit the x-axis at (3.6,0)
x=18
x=18
Solve, using the Rule of 72 rate = 4%, years = 18, fv=$8,000. Solve for PV. Formula: PV = $1/(1+r) t PV = $8000/(1+.04) 18 PV = $8000/2.0258 3949.03 = $8000/2.20258
U can subtract 18 from each side of the equation.
25-7=18 18/3=6
-3
18=3(3x-6)
0.5x=18 x=36
6c-18=4c Why can rearrange this and simplify to 2c=18, which means that c = 9
x - 13 = 5 x = 18
-18
x-18=34 solve for x add 18 both sides x-18+18=34+18 x=52
