Solving Equations
x + 58 = 122
x = 64
13 + 16 = 20 + 29
YES both sides are 29
Write & solve the equation: Mrs. O'Toole has 26 pencils at the beginning of the day, and 7 at the end. How many pencils did her students use?
Can be:
7 + y = 26
OR
26 - 7 = y
y = 19 pencils were used
Write this inequality in words:
x < 12
X is less than 12
4y + 5 = 25
164 - m = 36
m = 28
17 + 34 = 22 + 19
NOPE!
Write & solve the equation:
Kerry has $122 to spend! She buys some things at dollarama, and is left with $43. How much did she spend?
122 - y = 43
y = 79
She spend $79 at dollarama
Write this inequality in words:
x > 16
X is greater than or equal to 16
3m - 3 =18
m = 7
45 ÷ p = 5
p = 7
38 + 92 = 99 + 31
yes- both are 130
Nicole buys 8 cases of pop. She now has 96 cans of pop.
How many cans of pop (p) are in each case?
8 x p = 96
p = 12
2x + 5 > 15
x > 5
30 ÷ m + 2 = 7
m = 6
y ÷ 7 = 18
y = 126
Which numbers follow this inequality?
x > 15
16, 18, 11, 13, 14
16 and 18!
Jeremy is climbing Mount Everest to Base Camp. It is 5,464m high. He stops for a
break with 1,100m left. How many metres has he climbed (c) already?
5,464 - c = 1,100
OR
1,100 + c = 5,464
c = 4,300m
Solve this inequality:
5m - 3 < 27
m < 5
49 ÷ m + 2 = 9
m = 7
x - 1,263 = 2,364
x = 3627
Which numbers follow this inequality?
x < 22
18, 25, 28, 11, 9
18, 11, 9
x is less than 22
Write the equation and solve:
Mrs. Morrow has 12 classes in her school, and and has 60 chromebooks. She wants to give an even amount to each class- how many does each class get?
Can be:
12x = 60
or
60 divided by x = 12
x=4
Solve this inequality:
m ÷ 4 - 2 > 14
m > 3
m ÷ 8 - 17 = 23
m = 5
