Answer 2

MATH

SOLUTION:-1

5x-(-8)=38

=>5x+8=38

=>5x=38-8

=>5x=30

$\because$x=50

SOLUTION:-2

$\frac{3x}{8}=15$

=>3x=120

X=40

SOLUTION:-3

3x-1=2x-$\frac{2}{3}$

=>3x-1=$\frac{6x-2}{3}=15$

=>9x-3=6x-2

=>9x-6x=-2+3

=>3x=1

X= $\frac{3}{1}$

SOLUTION:-4

3x+4(x-1)=$\frac{5}{2}$

=>3x+4x-4=$\frac{5}{2}$

=>7x-4=$\frac{5}{2}$

=>14x-8=5

=>14x=13

X=$\frac{13}{14}$

SOLUTION:-5

8x-4(x-3)=2x

=>8x-4x+12=2x

=>4x+12=2x

=>4x-2x=-12

=>2x=-12

X=-6
