Solve this system by Elimination 2x+y=2
4x+2y=-4

x= 1 - y/2

Step-by-step explanation:

1. Subtract y from both sides. 2x=2−y

2. Divide both sides by 22.

x=\frac{2-y}{2} x= 22−y

3. Simplify  \frac{2-y}{2}

22−y to  1-\frac{y}{2}1−2y.   and there u get ur answer x=1−2y

this is for "2x+y=2" btw hope this helped!

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
