3x+1=-5x+65
3x + 5x + 1 = -5x + 5x + 65
8x + 1 - 1 = 65 - 1
8x = 64
x = 8
Let's prove that by substitution.
3(8) + 1 = -5(8) + 65
25 = -40 + 65
25 = 25
Yep. x = 8
3x + 5x + 1 = -5x + 5x + 65
8x + 1 - 1 = 65 - 1
8x = 64
x = 8
Let's prove that by substitution.
3(8) + 1 = -5(8) + 65
25 = -40 + 65
25 = 25
Yep. x = 8
