Answer:Yes!


Step-by-step explanation:If you put 5 in every spot where the x varible is and solve the equations they both equal the answer.

7x+3x

7(5)+3(5)= 7 x 5=35, 3 x 5=15

35+15=50


9x+5

9(5)+5= 9 x 5= 45

45+5=50


Hope this helps!

Answer:

Yes

Explanation:

The first one is 35+15 because 7*5 is 35 and 3*5 is 15

The second one is 45+5 because 9*5=45

35+15=50

45+5=50

Yes, they are equal.
