Question 181163
How do you work 
{y=2x
{y=-6x+4

you can do this by substitution since you already know y=2x, you can replace the y in the second equation by 2x...

y = -6x + 4
2x= -6x + 4
2x+ 6x = -6x + 6x +4
8x = 0 + 4
8x = 4
8x/8 = 4/8
x = 1/2

now that you know x go back and find y by substitution also...

y = 2x 
y = 2(1/2)
y = 2/2
y = 1

so your answer is....
(1/2, 1)
