X(21)+x(4)=300 I need solving
Genrish500 [490]

Answer:

12

Step-by-step explanation:

21x + 4x = 300         Put brackets around the first two terms.

(21x + 4x) = 300        Pull the x outside the brackets. Use the distributive property.  Combine the left

25x = 300                 Divide by 25

25x/25=300/25        Do the division

x = 12
