Question

11x+4 1/2=4 1/4(2x-2) дам 30 балов​

Answer 1

11х + 4$\frac{1}{2}$ = 4$\frac{1}{4}$ * (2х - 2)

11х + 4 $\frac{1}{2}$ = 8$\frac{1}{4}$х - 8$\frac{1}{4}$

11х - 8$\frac{1}{4}$х = -8$\frac{1}{4}$ - 4$\frac{1}{2}$

11х - $\frac{33}{4}$х = -$\frac{33}{4}$ - $\frac{9}{2}$

2.75x = -$\frac{33+18}{4}$

2.75x = -$\frac{51}{4}$

2.75x = -12.75

x = -$\frac{12.75}{2.75}$ = $\frac{1275}{100}$: $\frac{275}{100}$

x = -$\frac{1275}{275}$ = -$\frac{51}{11}$
