Cost of electric mower = $300

Cost of gas mower = $450

Total number of mower = 25

Cost of total mower is at least = $6,000

Find:

Number of each mower equation

Computation:

Number of electric mower = a

Number of gas mower = b

So,

Equations

a + b ≤ 25 ........ Equation 1

300a + 450b ≤ 6000 ....... Equation 1

Consider the following system of equations.

Sidana [21]

Y = 6x - 6 therefore y - 6x = -6
y - 6x = 5
so:
-6 ≠ 5
There is no solution to this system.
==========================
$\left \{ {{y=6x-6} \atop {y-6x=5}} \right. \\ \left \{ {{6x-y=6} \atop {-6x+y=5 }} \right. \\ 0 \neq 11$
