Step-by-step explanation:
The problem is set up properly.
The factor of x was not properly multiplied by the first two terms of the trinomial. Terms were not combined correctly.
The proper multiplication and combining of terms is shown in the attachment. The green diagonal lines show the like terms that need to be combined to form the result.
Answer:
x = 5, y = 20
Step-by-step explanation:
if y = 4x and 3x+2y = 55 then we can subtitude y as x.
We know that y = 4x so we can write 4x wherever we see y.
3x + 2y = 3x + 2(4x) = 55
3x + 8x = 55
11x = 55
x = 5.
And if y = 4x = 4(5)
y = 20
The answer is 3.9
