Question

Математика: 1. 8x + 12 = 5x + 32. 3(2x + 1) + 7 = 43. 6 + 3(5x - 7) = 4x + 74. 317x – 4) - 4(6x + 5) = x5. 3x – 5(2x + 3) – 6(5x – 4) = -286.3(x + 21) + 2(x – 4) = 5(x + 11)​

Відповідь:1)8x+12=5x+38x-5x=3-123x=-9x=-32)3(2x+1)+7=36x+3+7=46x=4-106x=-6x=-13)6+3(5x-7)=4x+76+15x-21=4x+7-15+15x=4x+715x-4x=7+1511x=22x=2Покрокове пояснення:...

1. 8x + 12 = 5x + 32. 3(2x + 1) + 7 = 43. 6 + 3(5x - 7) = 4x + 74. 317x – 4) - 4(6x + 5) = x5. 3x – 5(2x + 3) – 6(5x – 4) = -286.3(x + 21) + 2(x – 4) = 5(x + 11)​

1. 8x + 12 = 5x + 3
2. 3(2x + 1) + 7 = 4
3. 6 + 3(5x - 7) = 4x + 7
4. 317x – 4) - 4(6x + 5) = x
5. 3x – 5(2x + 3) – 6(5x – 4) = -28
6.3(x + 21) + 2(x – 4) = 5(x + 11)
