d increased by 7 equals 13
d + 7 = 13
15 = x + 5
10 = x
x/2 = 12

(1, 3) (2, 6) (3, 9) (4, 12)
The product of 4 and g is 24
4 · g = 24 or 4g = 24
d + 6 = 14
d = 8
6r = 30
r = 5
Tell whether this is a true solution:
y = 3x ; ( 2 , 6 )
YES (6 = 6)
Fill in a table and write the ordered pairs for the x values 1, 2, 3, and 4 for the equation y = 2x + 1.
(1, 3) (2, 5) (3, 7) (4, 9)
12 fewer than t is 18
t - 12 = 18
y - 11 = 19
y = 30
g ÷ 3 = 10
g = 30
Tell whether this is a true solution:
y = 5x - 10 ; ( 2 , 5 )
NOT A SOLUTION (5 does not equal 0)

Milo collects cards. He starts with 16 cards and after increasing his collection by a number c he now has a total of 30 cards.
16 + c = 30
6 + h = 32
h = 26
108 = 9n
12 = n
Tell whether this is a true solution:
y = 2x - 3 ; ( 4 , 5 )
YES (5 = 5)

Lucy brings 12 pieces of gum and splits them between her friends, giving each friend 3 pieces. Use the variable f to represent the number of friends.
12 ÷ f = 3 or 12 ÷ 3 = f
13 + 5 = b - 2
20 = b
2w ÷ 5 = 4
w = 10
Tell whether this is a true solution:
y + 3 = 6x ; ( 3 , 15 )
