What is the value of x in the equation 0.2(x + 1) + 0.5x = β0.3(x β 4)?
Accepted Solution
A:
0.2(x+1)+0.5x=-0.3(x-4) Expand the brackets 0.2x+0.2= -0.3x+1.2 Subtract 0.2 from each side 0.2x= -0.3x+1 Add 0.3 to each side 0.5x=1 Divide by 0.5 on each side x= 1Β Γ· 0.5 =2 To check, you can substitute 2 into the places of x
