Answer:
x= 7 - 2y, y∈ ℝ
Step-by-step explanation:
Remove unnecessary parentheses
x-5 + (y+1) 2+4
Distribute 2 through the parentheses
x-5 + 2y+2+4
Calculate the sum
x-3 + 2y=4
Move the expression to the right-hand side and change its sing
x=4+3-2y
Add the numbers
x=7-2y
Write the solution x in parametric form
x=7-27,y∈ ℝ
