Answer:
x = 2, y = -1
Step-by-step explanation:
Now change the equation,
→ x + y = 1
→ y = 1 - x
Then the value of x will be,
→ 2x + y = 3
→ 2x + 1 - x = 3
→ x = 3 - 1
→ [ x = 2 ]
Therefore, the value of x is 2.
Now value of y will be,
→ y = 1 - 2
→ [ y = -1 ]
Hence, the value of y is -1.
(2, -1)
-------
x = 2
y = -1
<u>1st equation</u>:
rewrite
<u>2nd equation</u>:
Solve simultaneously:
When x = 2, y = 1 - x
y = 1 - 2
b=√119
a2+b2=c2
(5×5)+(b2) =(12×12)
25+b2=144
b2=144-25
b2= 119
all work is shown and pictured
x = 19 cm
3+3+2+5+6 = 19
(x-1)(x-9)
