Solve the system of equations using the substitution method. y = 7x – 16, y = 2(2x – 5) what is the solution? (, )

Solving the system of equations using the substitution method, the solution is: x=2 and y=-2

Step-by-step explanation:

(1) y=7x-16

(2) y=2(2x-5)

Substituting "y" of the equation (1) in the equation (2)

(2) 7x-16=2(2x-5)

Applying the distributive property to eliminate the parentheses on the right side of the equation:

7x-16=2(2x)-2(5)

Multiplying:

7x-16=4x-10

Solving for x: Subtracting 4x and adding 16 both sides of the equation:

7x-16-4x+16=4x-10-4x+16

3x=6

Adding like terms:

Dividing by 3 both sides of the equation:

3x/3=6/3

x=2

Replacing x by 2 in the equation (1):

(1) y=7(2)-16

y=14-16

y=-2

Solution: x=2 and y=-2

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
