Question 108006
{{{5-2x=3x-7x=25}}} This equation has two equal signs? Double check your problem



<hr>



#2



{{{5(d+4)=7(d-2)}}} Start with the given equation




{{{5d+20=7d-14}}} Distribute



{{{5d=7d-14-20}}}Subtract 20 from both sides



{{{5d-7d=-14-20}}} Subtract 7d from both sides



{{{-2d=-14-20}}} Combine like terms on the left side



{{{-2d=-34}}} Combine like terms on the right side



{{{d=(-34)/(-2)}}} Divide both sides by -2 to isolate d




{{{d=17}}} Divide


--------------------------------------------------------------

Answer:

So our answer is {{{d=17}}}

#3




{{{3g-3=3(7-g)}}} Start with the given equation




{{{3g-3=21-3g}}} Distribute



{{{3g=21-3g+3}}}Add 3 to both sides



{{{3g+3g=21+3}}} Add 3g to both sides



{{{6g=21+3}}} Combine like terms on the left side



{{{6g=24}}} Combine like terms on the right side



{{{g=(24)/(6)}}} Divide both sides by 6 to isolate g




{{{g=4}}} Divide


--------------------------------------------------------------

Answer:

So our answer is {{{g=4}}}

#4





{{{2z-1=4+z}}} Start with the given equation




{{{2z=4+z+1}}}Add 1 to both sides



{{{2z-z=4+1}}} Subtract z from both sides



{{{z=4+1}}} Combine like terms on the left side



{{{z=5}}} Combine like terms on the right side


--------------------------------------------------------------

Answer:

So our answer is {{{z=5}}}
