Name ________________________

1). Simplify these equations by combining like terms and then find X:

(I will simplify the first equation for you!)

a). X + X + X + X = 44

Simplify it: 4X = 44

X =______

b). X + 2X + X + X = 25

Simplify it:: __________________

X =______

c). X + 2X + 2X + X = 36

Simplify it: __________________

X =______

d). 3X + 5X = 56

Simplify it: ________

X =______

e). 5X - 3X = 18

Simplify it: __________________

X =______

f). 2X + 6X - 3X = 30

Simplify it: __________________

X =______

g). 5X - 3X + 2 = 16

Simplify it: __________________

X =______
