Answer:
x = -6
Step-by-step explanation:
You can insert the second equation in for the y-variable in the first equation
x + 4(2x+14) = 2
The next step is to distribute the 4
x + 8x + 56 = 2
Then we combine like terms
9x + 56 = 2
Subtract 56 from both sides
9x = -54
Divide by 9 on both sides
x = -6
Answer:
x = - 6; y = 2
Step-by-step explanation:
{x + 4y = 2
{y = 2x + 14
x = 2 - 4y
y = 2x + 14
y = 2(2 - 4y) + 14
y = 4 - 8y + 14
y + 8y = 14 + 4
9y = 18
y = 18/9
y = 2
x = 2 - 4y
x = 2 - 4×2
x = 2 - 8
x = - 6
I hope I've helped you.
