!!!!solve with algebra!!!! show work please

Answer 1

Let X = pounds of Bermuda grass needed.

(20 pounds bahia grass x $6.30) + ( X x $3.65) = (20 +X) x $4.90

Simplify:

126 + 3.65X = 98 + 4.90X

Subtract 3.65X from each side:

126 = 98 + 1.25X

Subtract 98 from each side:

28 = 1.25X

Divide both sides by 1.25

X = 28 / 1.25

X = 22.4 pounds required.
