Question

Solve : y=3.58•x+ 202.6 & y=2.3•x+160.7

Answer 1

Answer:

$x=-32.73\,,\,y=85.43$

Step-by-step explanation:

Given: $y=3.58x+202.6\,,\,y=2.3x+160.7$

To find: value of x and y

Solution:

$y=3.58x+202.6\,\,(i)\\y=2.3x+160.7\,\,(ii)$

From equation (i) and (ii),

$3.58x+202.6=2.3x+160.7\\3.58x-2.3x=160.7-202.6\\1.28x=-41.9\\x=\frac{-41.9}{1.28}=-32.73$

Put $x=-32.73$ in (i)

$y=3.58(-32.73)+202.6\\=-117.17+202.6\\=85.43$
