let x = " a number"
:
Write an equation for the given statement
:
Twice the sum of a number and 3 is the same as five times the number minus 1
minus four times the number.
2x + 3 = 5x - 1 - 4x
2x + 3 = x - 1
2x - x = -1 -3
x = -4
:
Check solution
2(-4) + 3 = 5(-4) - 1 - 4(-4)
-8 + 3 = -20 - 1 + 16
-5 = -5
