We have such question
2.25t+5=13.5t+14 /-2.25t (subtract both sides 2.22t)
2.25t-2.25t+5=13.5t-2.25t+14
5=11.25t+14 /-14 (subtract 14 both sides)
5-14=11.25t+14-14
-9=11.25t /:11.25 (divide both sides by 11.25)
$-9:11.25$
-0.8=x - its the answer

$2.25t+5=13.5t+14\ \ \ \ |subtract\ 5\ from\ both\ sides\\\\2.25t=13.5t+9\ \ \ \ |subtract\ 13.5t\ from\ both\ sides\\\\-11.25t=9\ \ \ \ \ |divide\ both\ sides\ by\ (-11.25)\\\\t=-\frac{9}{11.25}\\\\t=-\frac{900}{1125}\\\\\boxed{t=-0.8}$

BartSMP [9]

Answer:

Michael worked 4 hours and Landon worked 10 hours.

Step-by-step explanation:

Michael can iron 40 shirts each hour, so in xx hours he can iron 40x40x shirts. Landon can iron 20 shirts each hour, so in yy hours he can iron 20y20y shirts. The total number of shirts ironed 40x+20y equals 360:

40x+20y=360

Since Michael and Landon worked a combined 14 hours, we know x+yx+y must equal 14.

x+y=14

Write System of Equations:

40x+20y= 360

x+y=14

Solve for y in each equation:

40x+20y = 360 x+y = 14 20y = -40x+360

$\frac{-20y}{20}$ = $\frac{-40x+360}{20}$
