Answer:

Step-by-step explanation:
The slope-intercept formula is:

y= keep as variable
m= slope of the line
x= keep as variable
b= y-intercept of the line.

Explanation:
When we have variables on both sides we look for the coefficient that is lower than the two and reverse the sign.
Example:
1x+ 4 = 2x+3
We reverse 1x sign because it is lower so we will be subtracting
2x-1x = 1x
1x+3=4
We would then solve for x.

Let's begin to solve! </span>
Step 1:You would look for the coefficient or variable that is less and reverse the sign.
In this question the lower number is -x and so we would reverse the sign to add.
x+x= 2
Step 2: We now have
2x+3 = -5
Step 3: We will subtract 3 to -5 to find X
-3+-5= -8
Step 4:2x = -8
Divide both sides by two fo find x
Our answer:

-
Summary:
We first looked for the lower coefficient (in this case variable). We then flipped the sign and solved for x

Answer:
80 m
Step-by-step explanation:
Given :-
One side of rhombus = 20 m.
[ as one of the property of rhombus = all sides are equal ]
So, perimeter of rhombus = sum of all sides
= 20+20+20+20 = 80 m
...........................OR............................
Perimeter of rhombus = 4 × side
= 4 × 20 = 80 m
Hence, the perimeter of the rhombus is 80m.
