Question

Solve:
x-1/2–5x+9/28=x+6/21+5–x+12/3​

Answer 1

x-1/2–5x+9/28=x+6/21+5–x+12/3

42(x+1)−3(5x+9)=4(x+6)+420−28(x−12)

42x+42−3(5x+9)=4(x+6)+420−28(x−12)

42x+42−15x−27=4(x+6)+420−28(x−12)

27x+42−27=4(x+6)+420−28(x−12)

27x+15=4x+24+420−28(x−12)

27x+15=4x+444−28x+336

27x+15=−24x+444+336

27x+15=−24x+780

27x+15+24x=780

51x+15=780

51x=780−15

51x=765

x= 765/51

x=15
