Step-by-step explanation:
So we have the expression:

Combine like terms:

Add or subtract:

Simplify:

Our answer is D
Let x be the number of child tickets he bought
Let y be the number of adult tickers he bought
① x+y=7 (child tickets+adult ticket=7 tickets in total)
② 2x+4y=24 (price of child tickets+price of adult tickets=$24 in total)
We may simply the second equation since all of the coefficients are divisible by 2.
① x+y=7
② x+2y=12
We can now use elimination by multiplying the second equation by -1.
② -(x+2y=12)
② -x-2y=-12
① x+y=7
② -x-2y=-12
Now putting the equations together,
-y=-5
y=5
x=2
Therefore he bought 2 child tickets and 5 adult tickets

Step-by-step explanation:
Start from left one first
12x & 70
Area as Sum= 12x+70
Area as Product = 12(x+5)
Right side
X & 4
Area as Sum= 5X+20
Area as Product = 5(X+4)
