Answer:
x = 2
Step-by-step explanation:
3(x - 1) = 23 - 5(x + 2) ← distribute parenthesis on both sides
3x - 3 = 23 - 5x - 10
3x - 3 = 13 - 5x ( add 5x to both sides )
8x - 3 = 13 ( add 3 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
10 times the value because the 2 in 21 is 2 tens which is 20 and the two in 82 is 2 ones so just 2. 2 times 10 is 20 so your answer is 20 times the value.
