-3|x+5| + 1 = 7|x+5| + 8 Solution:
-3|x+5| – 7|x+5| = 7
-10 |x+5| = 7
|x+5| = -7/10
x+5 = ±(-7/10)
x = ±(-7/10) – 5
x₁ = -7/10 – 5
x₁ = -57/10
x₂ = 7/10 – 5
x₂ = 2/10
x₂ = 1/5
Correct?
-3|x+5| – 7|x+5| = 7
-10 |x+5| = 7
|x+5| = -7/10
x+5 = ±(-7/10)
x = ±(-7/10) – 5
x₁ = -7/10 – 5
x₁ = -57/10
x₂ = 7/10 – 5
x₂ = 2/10
x₂ = 1/5
Correct?
