Answer:
x= 6/7z
Step-by-step explanation:
5x + 4z = 10z - 2x
5x + 2x = 10z - 4z
7x = 6z
x = 6/7z
Answer: 5x + 4z = 10z - 2x
move variable to the left side and change its sign
5x + 2x + 4z +10
Move variable to the right side and change its sign. 5x + 2x = 10z - 4z Collect the like terms 5x + 2x =10z - 4z ↓ 7x = 10z - 4z Collect the like terms ↓ 7x = 6z Divide both sides of the equation by 7 x = 6/7 z decimal 0.857143
