How would I solve the equations: y = x-4 and y=x^2-4x using substitution

Mathematics
1 answer:
andriy [413]3 years ago
6 0

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
