How would I solve the equations: y = x-4 and y=x^2-4x using substitution
1 answer:
Answer:
x = 6
Explanation:
y = x - 4
26 = 4x + y
If y = y, then we can rewrite this system as this: 4x + x - 4 = 26
Then we combine like terms and add 4 on both sides to give us 5 x = 30
. Divide by 5 on both sides and we arrive at the solution: x = 6
