The angles are set to equal to eachother since alternate interior angles are congruent
so 6x+5=4x+45
Solve for X
-5 from both sides
6x=4x+40
-4x both sides
2x=40
÷2 both sides
X=20
Now plug in the answer for X in angle A to figure out what degree angle A is 6x+5
6 (20)+5
120+5
Given:
The system of equations:


To find:
The number that can be multiplied by the second equation to eliminate the x-variable when the equations are added together.
Solution:
We have,
...(i)
...(ii)
The coefficient of x in (i) and (ii) are 1 and
respectively.
To eliminate the variable x by adding the equations, we need the coefficients of x as the additive inverse of each other, i.e, a and -a So, a+(-a)=0.
It means, we have to convert
into -1. It is possible if we multiply the equation (ii) by -5.
On multiplying equation (ii) by -5, we get
...(iii)
On adding (i) and (iii), we get

Here, x is eliminated.
Therefore, the number -5 can be multiplied by the second equation to eliminate the x-variable.
If he knows that he is doubling his recipe then first he needs to know how many tablespoons of breadcrumbs he needs. 3 * 2 = 6 tablespoons. Because he is using half tablespoons he needs to multiply that by 2 again. 6 * 2 = 12.
