3.Solve the system of equations: X-4y=-22 x+4y=10​
laila [671]

Answer:

-0.5

Step-by-step explanation:

Use the simultaneous equations method:

x - 4y = 6

3x + 4y = 10

Add these two equations together to cancel out 'y':

4x = 16

Divide both sides by 4:

x = 4

substitute this value into one of the equations:

(4) - 4y = 6

Subtract 4 from both sides:

- 4y = 2

Divide both sides by -4:

y = -0.5

goodluck!

X^3+x^3+1=341
2x^3+1=341
Substrate 1 from both sides
2x^3=341-1
