Solve<br><br> 1/5 (x+3)=−(2x+3)

Rasek [7]

Answer:

Step-by-step explanation:

just simplify the LHS first.

You can either multiply 1/5 by (x+3) and then solve

multiply both sides by 5 to get rid of 1/5 on LHS

I will multiply by 5

(x+3)= -10x-15 ( 5*1/5(x+3)= -5(2x+3)

now rearrange the equation

x+3=-10x-15

-10x-15-x-3=0

-11x-17=0

-11x=17

x= -17/11

Answer:

2x+5

Step-by-step explanation:

Formula for the perimeter of a reactangle= 2(l+b)

So,

2(l+b) = 10x+18

2(3x+4 + b) = 10x+18

Rearrange and solve

3x+4+b = 5x+9

b = 5x+9 - 3x - 4

b = 2x+5

Thus the measurement of the width = 2x+5

Hope this helps
