4x*5=

2/3x*3=

3/4x*1/3=

2x*(-6)=

(-2)*0,5x=

(-1/5x)*(-2)=

(-x)*(-2/3)=

2*(x+3)=

5*(3x-1)=

(-4)*(2a-b)=

-2*(-4b+3)=

(a+b)*(-4)=

(4-5x+6y)*3=

-3*(3x-2)=

-1*(3x-y+2)=

(10+2y)/2=

(-3a+12)/(-3)

(24a-4b)/8=

(4u-6v)/(-1/2)=

Answer 1

2*3x=6x

4x*5=20x

2/3x*3=2x

3/4x*1/3=1/4x

2x*(-6)=(-12x)

(-2)*0,5x=(-1x)

(-1/5x)*(-2)=2/5x

(-x)*(-2/3)=2/3x

2*(x+3)=2x+6

5*(3x-1)=15x+(-5)

(-4)*(2a-b)=(-8a)- 4b

(-2)*(-4b+3)=8b+(-6)

(a+b)*(-4)=(-4a)+(-4b)

(4-5x+6y)*3=12+(-15x)+18y

(-3)*(3x-2)=(-9x)+6

(-1)*(3x-y+2)=(-3x)-y+(-2)

(10+2y)/2= y=5

(-3a+12)/(-3)=a=(-4)

(24a-4b)/8= a = 3  b = 1/2

(4u-6v)/(-1/2)=u=8  v=12
