Answer:
3x +2y -7
Step-by-step explanation:
The given expression can be simplified by combining like terms. Those are terms with the same variable. The commutative and associative properties of addition apply, as well as the distributive property.
(2x +3y -7) +(x -y) . . . . . given
= 2x +3y -7 +x -y . . . . . . eliminate (unneeded) parentheses
= (2x +x) +(3y -y) -7 . . . . group like terms
= (2+1)x +(3-1)y -7 . . . . . . combine coefficients of like terms (this is an application of the distributive property)
= 3x +2y -7

Cost of one hosta is $11 and one pot of ivy is $4.
Step-by-step explanation:
Let,
Cost of one hosta = x
Cost of one pot of ivy = y
According to given statement;
3x+5y=53 Eqn 1
x+7y=39 Eqn 2
Multiplying Eqn 2 by 3
Subtracting Eqn 1 from Eqn 3
Dividing both sides by 16
Putting y=4 in Eqn 2
Cost of one hosta is $11 and one pot of ivy is $4.
