Solve the following system of equations. x + 2y − 6 = z 3y − 2z = 7 4 + 3x = 2y − 5z

3y-2z=7

y=......equation(1)

Given x+2y-6=z

x=z-2y+6

putting value of y from equation(1)

By simplifying x=.....Equation(2)

Now putting the value of x and y in term of z in 3rd given equation

i.e 4+3x=2y-5z

i.e 2y-5z-3x=4

i.e 2()-5z-3()=4

By simplifying we will get -8z+14=24

i.e z=

Now putting z value in Equation(1);y=3/4

And putting z value in Equation(2);x=7/3 (Answer)

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

the one below it is a function
