1/4 (3u-13)=2-u

\frac{1}{4} (3 u - 13) = 2 - u

u = 3

Solution steps

\frac{1}{4} (3 u - 13) = 2 - u

Expand

\frac{1}{4} (3 u - 13) : \frac{3}{4} u - \frac{13}{4}

\frac{3}{4} u - \frac{13}{4} = 2 - u

Move

\frac{13}{4}

to the right side

\frac{3}{4} u = - u + \frac{21}{4}

Move

u

to the left side

\frac{7}{4} u = \frac{21}{4}

Multiply both sides by

4

7 u = 21

Divide both sides by

7

u = 3

(8 s + 9)^{2} = 4

3 n - 2 = 7

90 = w^{2} + 5 w + 6

576 = 16 t^{2}

\frac{7 + 3}{7 - 3}
