A. -3x –9 = 0
B.4 + 3(z -8) = -23
C.1 –2(y –4) = 5
IF YOU DON'T KNOW THE ANSWER THEN DON'T TYPE ANYTHING

Answer 1

Step-by-step explanation:

A. -3x - 9 = 0

• -3x = 9
• -x = $\frac{ 9 }{ 3 }$
• -x = 3
• x = -3

B. 4 + 3 (z - 8) = -23

• 4 + (3z - 24) = -23
• 3z - 24 = - 23 - 4
• 3z - 24 = - 27
• 3z = - 27 + 24
• 3z = -3
• z = $\frac{ -3}{3}$
• z = -1

C. 1 - 2 (y - 4) = 5

• 1 - (2y - 8) = 5
• 2y - 8 = 5 - 1
• 2y - 8 = 4
• 2y = 4 + 8
• 2y = 12
• y = $\frac{ 12}{6}$
• y = 2
