Simplify the expression: 3x + 5x
8x
Simplify the expression: 7y - 4y + 2
3y + 2
Simplify using the distributive property: 2(a + 3)
2a + 6
Simplify using the distributive property: 3(2x + 5)
6x + 15
Solve for x: x + 7 = 12
x = 5
Solve for y: 3y - 4 = 11
3y = 15 → y = 5
Solve for x: 5x + 2 = 17
5x = 15 → x = 3
Solve for z: 2(z - 3) = 10
2z - 6 = 10 → 2z = 16 → z = 8
Identify the next number in the sequence: 2, 4, 6, 8, …
10
Identify the next number in the sequence: 3, 6, 12, 24, …
48
Identify the next number in the sequence: 10, 7, 4, 1, …
-2
A number is increased by 7 and then doubled. Write an expression for this operation.
2(x + 7)
Solve for x: 4x - 3 = 9
4x = 12 → x = 3
Solve for y: 5 + 3y = 20
3y = 15 → y = 5
Solve for x: 6 - 2x = 10
-2x = 4 → x = -2
