Jim and Sally mow lawns in their neighborhood. Sally mows 5 less than twice the number of lawns Jim mows. Together they mow 25 lawns. Which system of equations models this situation if j represents the number of lawns Jim mows and s represents the number of lawns sally mows?

s=2j+5

s=25−j

j=2s−5

j+s=25

s=2j−5

s+j=25

j=2s+5

j=25−m

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

there are infinitely many solutions.
