How would I do this -1/2x+2=-x+7

x=10

Step-by-step explanation:

-x+4=-2x+14        Multiply both sides of the equation by 2

-x+2x+4=14         Move the variable to the left side and change its sign

-x+2x=14-4

-x+2x=14-4          Collect the like terms

x=14-4                Subtract the numbers

x=10

Hope this helps! :)

would also appreciate a brainliest mark

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
