Question

Please answer these questions and explain how you did it (plz help me due tomorrow)

1)3/4(1/2x+1/5)-1/8x=2 1/5
2)14(3x+5)-4(2x-12)=262
3)0.025x-14.8=7.45
4)5(3x-2)=2.5(2x+6)

Answer 1

first one I just answerd, the answer is x=8.2 or 8 and 1/5

2nd one
divide both sides by 2 and distribute
21x+35-4x+24=131
17x+59=131
minus 131 both sdes
17x=72
divide both sides by 17
x=72/17





3.
add 14.8 to both sides
0.025x=22.25
divide both sides by 0.025
x=890




4.
divide oth sides by 2.5
2(3x-2)=2x+6
expand
6x-4=2x+6
minus 2x both sides
4x-4=6
add 4 both sides
4x=10
divide by 4
x=10/4=5/2
