Question

Please solve the 4th one’s i and iv

Answer 1

Answer:

for (i) x=4

Step-by-step explanation:

5(x+1)=25

5x+5.1=25

5x+5=25

5x=25-5

5x=20

x=20/5=4

x=4

Answer 2

$\huge\star{\tt{\underline{\underline{\red{Answer}}}}}\star$

(i)5x-6=12-x

5x+x=6+12

$\implies$ 6x=18

$\implies$ $\large{x=\frac{18}{6}}$

$\implies$ $\large{\boxed{\boxed{x=3}}}$

(ii)2x + $\frac{5}{2}$ =$\frac{2}{3}$ - x

$\frac{5}{2}$ -$\frac{2}{3}$ =- x-2x

$\implies$$\large\frac{15-4}{6}$ = -3x

$\implies$ $\large\frac{11}{6}$ = -3x

$\implies$ $\large\frac{-11}{6 x 3}$= x

$\implies$ $\large{\boxed{\boxed{x= \frac{-11}{18}}}}$
