Question

Given the system of linear x+4x=11 -5+y=2x

Answer 1

x = 2.2 and y = 9.4 → (2.2, 9.4)

Explanation:

`(1)\qquad x+4x=11\\(2)\qquad -5+y=2x\\\\(1)\\5x=11\qquad\text{divide both sides by 5}\\\boxed{x=2.2}\\\\\text{Put the value of x to (2):}\\-5+y=2(2.2)\\-5+y=4.4\qquad\text{add 5 to both sides}\\\boxed{y=9.4}`
