2x-3 = 6
2x(-3+3) = (6+3)
2x = 9
(2x ÷ 2) = (9 ÷ 2)
x = 4.5
Answer:
x=13
Step-by-step explanation:
ok so let x+y=22
--------------------------------------------------------
x and y are the 2 unkown Number
-------------------------------------------
x-y=4
their difference is 4
----------------------------------
add both equations
(x+y=22)
+(x-y=4)
------------------------------
y's cancel out
-----------------------
2x=26
-----------------
x=13
Answer:
there has to be a graph or table right?
Step-by-step explanation:
Answer:
90.
Step-by-step explanation:
We have two lines of code:
y ← x + x + x + x + x
z ← y + y + y
and, x=6 before the execution. Then, when the program starts to run we obtain:
y ← 6 + 6 + 6 + 6 + 6
y ← 30
z ← 30+30+30
z ← 90.
Then, the value of z after excecution is 90.
3x = 5y - 1
(3,3)...not a solution
(7,4)...not a solution
(-1/3,0)...is a solution
(-2,-1)...is a solution
