1/4(X-10)=2X+1 <br><br> what is X?
In-s [12.5K]

Answer: x=-2

Step-by-step explanation:

\frac{1}{4}(x-10)=2x+1

Distribute 1/4

\frac{1}{4}x-\frac{1}{4}(10)=2x+1

\frac{1}{4}x-\frac{5}{2}=2x+1

add 5/2

\frac{1}{4}x-\frac{5}{2}+\frac{5}{2}=2x+1+\frac{5}{2}

\frac{1}{4}x=2x+\frac{1*2+5}{2}

\frac{1}{4}x=2x+\frac{2+5}{2}

\frac{1}{4}x=2x+\frac{7}{2}

Subtract 2x

\frac{1}{4}x-2x=2x-2x+\frac{7}{2}

\frac{1}{4}x-2x=\frac{7}{2}

\frac{1-2*4}{4}x=\frac{7}{2}

\frac{1-8}{4}x=\frac{7}{2}

-\frac{7}{4} x=\frac{7}{2}

Multiply by the negative reciprocal of -7/4 which is basically inverting the fraction -4/7

(-\frac{4}{7} )-\frac{7}{4} x=\frac{7}{2}(-\frac{4}{7} )

x=-\frac{28}{14}\\ x=-2
