Solve the following equation for x: 6(4x+5)= 3(x+8)+3. Round to the nearest hundredth.
2 answers:
6(4x + 5) = 3(x + 8) + 3
24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
24x - 3x = 27 - 30
21x = - 3
x = -3/21
x = - 0.143 <==
Hey there! :D
6(4x+5)=3(x+8)+3
Distribute.
24x+30=3x+24+3
24x+30=3x+27
Subtract 30 on both sides.
24x= 3x-3
Subtract 3x on both sides.
21x=3
Divide both sides by 21.
x=0.142857... the question said hundredth so:
x=0.143
I hope this helps!
