3(у - 3) - 2(у 4) = 4

y = 5

Step-by-step explanation:

3(у - 3) - 2(у -4) = 4

Distribute

3y -9 -2y +8 =4

Combine like terms

y -1 =4

Add 1 to each side

y-1+1 = 4+1

y = 5

y = 5

Step-by-step explanation:

So I'm gonna assume this is 3(y-3) - 2(y-4) = 4

Use the distributive property

3y - 9 - 2y + 8 = 4

y - 1 = 4

y = 5

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°
