Issolvi z=15/4-5/2*7/5*2

$$z = \frac { 15 } { 4 } - \frac { 5 } { 2 } \times \frac { 7 } { 5 } \cdot 2$$

Solvi għal z

$$z = -\frac{13}{4} = -3\frac{1}{4} = -3.25$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika \frac{5}{2} b'\frac{7}{5} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$z=\frac{15}{4}-\frac{5\times 7}{2\times 5}\times 2$$

Annulla 5 fin-numeratur u d-denominatur.

$$z=\frac{15}{4}-\frac{7}{2}\times 2$$

Annulla 2 u 2.

$$z=\frac{15}{4}-7$$

Ikkonverti 7 fi frazzjoni \frac{28}{4}.

$$z=\frac{15}{4}-\frac{28}{4}$$

Billi \frac{15}{4} u \frac{28}{4} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$z=\frac{15-28}{4}$$

Naqqas 28 minn 15 biex tikseb -13.

$$z=-\frac{13}{4}$$

Assenja z

$$z≔-\frac{13}{4}$$
