Answer/step-by-step explanation:
2(x + 5) = 3x + 1
2x + 10 = 3x + 1
Subtract 2x from both sides.
10 = x + 1
Subtract 1 from both sides.
9 = x
3y - 4 = 6 - 2y
Add 2y to both sides.
5y - 4 = 6
Add 4 to both sides.
5y = 10
Divide both sides by 5.
y = 2
3(n + 2) = 9(6 - n)
3n + 6 = 54 - 9n
Add 9n to both sides.
12n + 6 = 54
Subtract 6 from both sides/
12n = 48
Divide both sides by 12.
n = 4
