7(4x - 5) +9 = 4 (5x + 8) - 26 adalah k. Berapa nilai 4k +27

7 (4x - 5) + 9 = 4 (5x + 8) - 26
28x - 35 + 9 = 20x + 32 - 26
28x - 26 = 20x + 6
28x - 20x = 6 + 26
8x = 32
x = 32/8
x = 4
x = k, maka k = 4

4k + 27
= 4(4) + 27
= 16 + 27
= 43

Langsung aja y

7(4x-5)+9 = 4(5x+8) - 26
28x - 35 + 9 = 20x + 32 - 26
28x - 26 = 20x + 6
28x - 20x = 6 + 26
8x = 32
x = 4

7(4x-5)+9 = k
28x - 35 + 9 = k
28.4 - 26 = k
112 - 26 = k
86 = k

= 4k + 27
= 4.86 + 27
= 344 + 27
= 371

Semoga berguna +_+
