Q:
# Solve the equation .

Accepted Solution

A:

Answer:x = 10Step-by-step explanation:2x/3 + 1 = 7x/15 + 3(times everything in the equation by 3 to get rid of the first fraction)2x + 3 = 21x/15 + 9(times everything in the equation by 15 to get rid of the second fraction)30x+ 45 = 21x + 135(subtract 21x from 30x; subtract 45 from 135)9x = 90(divide 90 by 9)x = 10Another solution:2x/3 + 1 = 7x/15 + 3(find the LCM of 3 and 15 = 15)(multiply everything in the equation by 15, then simplify)10x + 15 = 7x + 45(subtract 7x from 10x; subtract 15 from 45)3x = 30(divide 30 by 3)x = 10
