Solve the system by substitution:
-3x + y = 7
5x + 2y = 3

4

Step-by-step explanation: 1] y = 3x + 7

// Plug this in for variable y in equation [2]

[2] 5x + 2•(3x+7) = 3

[2] 11x = -11

// Solve equation [2] for the variable x

[2] 11x = - 11

[2] x = - 1

// By now we know this much :

x = -1

y = 3x+7

// Use the x value to solve for y

y = 3(-1)+7 = 4

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°
