2-step equations
2x + 5 = 11
Subtract 5 from both sides: 2x = 6
Divide both sides by 2: x = 3
x + 5 < 9
Subtract 5 from both sides: x < 4
2x < 10
Divide both sides by 2: x < 5
2x + 3 < 9
Subtract 3 from both sides: 2x < 6
Divide both sides by 2: x < 3
1/5 + 2/5 = ?
3/5
3y - 7 = 8
Add 7 to both sides: 3y = 15
Divide both sides by 3: y = 5
y - 3 ≥ 6
Add 3 to both sides: y ≥ 9
y/3 ≥ 4
Multiply both sides by 3: y ≥ 12
3y - 5 ≥ 10
Add 5 to both sides: 3y ≥ 15
Divide both sides by 3: y ≥ 5
1/3 + 1/4 = ?
Find a common denominator (12): 4/12 + 3/12 = 7/12
a/4 + 3 = 6
Subtract 3 from both sides: a/4 = 3
Multiply both sides by 4: a = 12
a + 7 ≤ 2
Subtract 7 from both sides: a ≤ -5
5a ≤ -15
***** DAILY DOUBLE *****
Divide both sides by 5: a ≤ -3
a/4 + 2 ≤ 5
Subtract 2 from both sides: a/4 ≤ 3
Multiply both sides by 4: a ≤ 12
2/3 x 3/4 = ?
(2 x 3) / (3 x 4) = 6/12
Simplify: 1/2
5b - 9 = 2b + 6
Subtract 2b from both sides: 3b - 9 = 6
Add 9 to both sides: 3b = 15
Divide both sides by 3: b = 5
b - 4 > -10
Add 4 to both sides: b > -6
-4b > 20
Divide both sides by -4 (and remember to flip the inequality sign): b < -5
-5b + 7 > -8
***** DAILY DOUBLE *****
Subtract 7 from both sides: -5b > -15
Divide both sides by -5 (and remember to flip the inequality sign): b < 3
3/5 ÷ 1/2 = ?
Invert and multiply: 3/5 x 2/1 = 6/5
Or as a mixed number: 1 1/5
(2c + 1)/3 = 5
Multiply both sides by 3: 2c + 1 = 15
Subtract 1 from both sides: 2c = 14
Divide both sides by 2: c = 7
-8 + c ≥ -15
Add 8 to both sides: c ≥ -7
c/-2 < -6
Multiply both sides by -2 (and remember to flip the inequality sign): c > 12
(2c - 1)/3 < 3
Multiply both sides by 3: 2c - 1 < 9
Add 1 to both sides: 2c < 10
Divide both sides by 2: c < 5
2 1/2 - 1 1/4 x 2/3 = ?
Convert mixed numbers to improper fractions: 5/2 - 5/4 x 2/3
Multiply fractions first: 5/4 x 2/3 = 10/12 = 5/6
Find a common denominator (6): 15/6 - 5/6 = 10/6
Simplify: 5/3
Or as a mixed number: 1 2/3
