3(2x+5) + 2x = x+50

Hint: x+50
-x
x=5

Answer 1

3(2x+5) + 2x = x+50
first you distribute the three to the numbers in the parentheses so it would be
6x +15 +2x = x+50 then add the common numbers (the ones with x and the ones without)
8x + 15 = x+ 50 now isolate the variable so subtract 1x from both sides since it’s a positive 7x +15 =50 and then subtract 15 from both sides: 7x= 35 then divide 35 by 7
x= 5.
