Answer:
- x = -1/2
- x = -1/2
- x = -14/5
- x = 3
Explanation:
1) 3(2x + 9) = 24, find x?
→ 3(2x + 9) = 24
→ 6x + 27 = 24
→ 6x = 24 - 27
→ x = -3/6
→ [ x = -1/2 ]
Hence, value of x is -1/2.
2) 4x - 2 = 10x + 1, find x?
→ 4x - 2 = 10x + 1
→ 4x - 10x = 1 + 2
→ -6x = 3
→ x = -3/6
→ [ x = -1/2 ]
Hence, value of x is -1/2.
3) 3x - 4(2x + 1) = 10, find x?
→ 3x - 4(2x + 1) = 10
→ 3x - 8x - 4 = 10
→ -5x = 10 + 4
→ [ x = -14/5 ]
Hence, value of x is -14/5.
4) 3x + 10 = 19, find x?
→ 3x + 10 = 19
→ 3x = 19 - 10
→ x = 9/3
→ [ x = 3 ]
Hence, value of x is 3.
