Answer

y = -$\frac{-7}{4}$

Work Step by Step

24y -10 =20y -17 Add 10 to both sides 24y -10 +10=20y -17 +10 24y = 20y -7 Subtract 20y from both sides 24y -20y = 20y -7 -20y 4y = -7 y =-$\frac{7}{4}$ Check Replace y with -$\frac{7}{4}$ 24y -10 =20y -17 24$\times$ $\frac{-7}{4}$ -10 =20 $\times$ $\frac{-7}{4}$- 17 -$\frac{6\times4\times7}{4}$ -10 = -$\frac{5\times4\times7}{4}$- 17 -42 -10 = -35 -17 -52 = -52
