jika 7(4x - 16) = 4(2x + 6), maka nilai dari x - 5 adalah....

[tex]7(4x - 16) = 4(2x + 6) \\ 28x - 112 = 8x + 24 \\ 28x - 8x = 24 + 112 \\ 20x = 136 \\ x = \frac{136}{20} \\ x = 6.8 \\ 6.8 - 5 = 1.8[/tex]

7(4x - 16) = 4(2x + 6)
28 x - 112 = 8x + 24
28x - 8x = 24 + 112
20 x = 136
x = 136/20
x = 34/5

nilai dari x - 5
= 34/5 - 5
= 34/5-25/5
= 9/5
= 1 ⁴/5
