Question

X+y=180 x=10y+48 (With Steps Plz)

Answer 1

Answer:

(168,12)

Step-by-step explanation:

Substitute x = 10y+48 in the first equation.

$10y + 48 + y = 180 \\ 11y = 180 - 48 \\ 11y = 132 \\ y = \frac{132}{11} \\ y = 12$

We have got the y-value. Our next goal is to find the x-value by substituting y-value in any given equations.

For me, I will be substituting y = 12 in the first equation.

$x + 12 = 180 \\ x = 180 - 12 \\ x = 168$

Answer Check

Substitute both x-value and y-value in both equations.

$168 + 12 = 180 \\ 180 = 180$

Our first equation is true for both values.

$168 = 10(12) + 48 \\ 168 = 120 + 48 \\ 168 = 168$

Our second equation is true for both values.

Thus, the answer is (168, 12)
