Answer:
x = 3 and y = -1
Step-by-step explanation:
It is given that,
3x + 2y = 7 ----(1)
2x - 5y = 11 ---(2)
<u>To find the solution of given equations</u>
eq(1) * 2 ⇒
6x + 4y = 14 ----(3)
eq(2) * 3 ⇒
6x - 15y = 33 ----(4)
eq(3) - eq(4) ⇒
6x + 4y = 14 ----(3)
<u>6x - 15y = 33 </u> ----(4)
19y = 19
y = -1
Substitute the value of y in eq (1) we get,
3x + 2y = 7 ----(1)
3x + (2 *-1) = 7
3x = 7 + 2 = 9
x = 9/3 = 3
Therefore x = 3 and y = -1

Answer:
a. y = 2x b. 32
Step-by-step explanation:
a, y = kx, where k is a non-zero constant
when x = 7, y = 14
14 = 7k
k = 2
The required equation is y = 2x
b. From(a), y = 2x
y = 2(16)
y = 32
Top left: y=2x+2
Top right:y=3x-1
Bottom left: y=-1x+1
Bottom right: y=-1/3x+2
