Solve the system of equations using elimination x+y=13, -x+2y=11 QWhat is the solution, and type an ordered pair.

Assuming the sign is a rectangle --

P = 2L + 2W

128 = 2(W + 6) + 2W
128 = 4W + 12
116 = 4W
29 = W

Solve the system of equati(a) symbolically,(b) graphically, and (c) numericallyons6x+2y= 6, -12x +3y = - 12. Find the ordered pair or is it innitely with many solutions or no sultion. i need to graph it also. And also i need to complete the table of values. y = -3x +3, y = 4x -4 and find a odered pair and graph it

I'm sorry you didn't understand my directions above.

x+y=13, -x+2y=11 QWhat is the solution, and type an ordered pair.

x + y = 13
-x + 2y = 11 add the two equations to eliminate x
------------
0 + 3 y = 24
y = 8
go back and get x
x + 8 = 13
x = 5
(5,8)

6x+2y= 6, -12x +3y = - 12. Find the ordered pair or is it innitely with many solutions or no sultion.
-------------------------------
double the first equation
+12 x + 4 y = +12
-12 x + 3 y = -12
------------------
7 y = 0
y = 0
go back and get x
12 x + 0 = 12
x = 1
(1,0)

i need to graph it also. And also i need to complete the table of values. y = -3x +3, y = 4x -4 and find a odered pair and graph it

A hardware supplier manufactures three kinds of clampos. Types A,B,C. Productionrestrictions force it to make 20 more type C clamps than the total of the othertypes and twice as many type B clamps as type A clampos. the shop must producew 320 clamps per day . How many of each type are made per day. how many type a clamps are produced? How many type B clamps are produced. How nmany type C clamps are produced?

y = -3x +3, y = 4x -4 and find a odered pair and graph it
y = -3x + 3
y = +4x - 4 subtract
-------------------
0 - -7 x + 7
7x=7
x = 1
go back for y
y = -3(1) + 3
y = 0
so
(1,0)

To graph these lines look for the x and y axis intercepts
for example for the line
y = -3 x + 3
when x = 0, y = 3 so mark (0,3)
when y = 0, x = 1 so mark (1,0)
draw a straight line through those two points.

• math -

c = 20 + a + b
b = 2 a
a + b + c = 320
-------------------
-------------------
substitute 2 a for b
c = 20 + a + 2 a = 20 + 3 a

a + 2 a + 20 + 3 a = 320
6 a = 300
a = 50
then b = 100
then c = 20+150 = 170
