36x+32=32x-36 whats the value of x

bulgar [2K]

Answer:

$x = -17$

Step-by-step explanation:

Step 1: Subtract 32x from both sides

$36x + 32 - 32x = 32x - 36 - 32x$

$4x + 32 = -36$

Step 2: Subtract 32 from both sides

$4x + 32 - 32 = -36 - 32$

$4x = -68$

Step 3: Divide both sides by 4

$4x / 4 = -68 / 4$

$x = -17$

Answer: $x = -17$

a 1 = 3 · ( -2 ) ^0 = 3
a 2 = 3 · ( - 2 ) = - 6
a 3 = 3 · 4 = 12
a 4 = 3 · ( - 8 ) = - 24
a 5 = 3 · 16 = 48
