Answer:

x = 1/3 and y = 3

Step-by-step explanation:

It is given the system of equations

3x + 2y = 7   ----(1)

-3x + 3y = 8    ----(2)

<u>To find the solution</u>

Add eq(1) and eq (2) we get,

3x + 2y = 7   ----(1)

<u>-3x + 3y = 8</u>    ----(2)

 0 + 5y = 15

y = 15/5 = 3

Substitute the value of y in eq(1)

3x + 2y = 7   ----(1)

3x + 2*3 = 7

3x + 6 = 7

3x = 7 - 6 = 1

x = 1/3

Therefore

x = 1/3 and y = 3

What are the solutions of the quadratic equation? 2 x^2 – 16 x + 32 = 0
White raven [17]

Answer:

X=4,4

Step-by-step explanation:

2 x^2 – 16 x + 32 = 0

2(x^2-8x+16)=0

X^2-(4+4)X+16=0

x^2-4x-4x+16=0

x(x-4)-4(x-4)=0

(x-4)(x-4)=0

X=4,4

So the solution is X=4,4
