Answer:

x = 1.75y + 0.25z

Explanation:

Simplifying

4x + -7y = z

Solving

4x + -7y = z

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

4x + -7y + 7y = 7y + z

Combine like terms: -7y + 7y = 0

4x + 0 = 7y + z

4x = 7y + z

Divide each side by '4'.

x = 1.75y + 0.25z

Simplifying

x = 1.75y + 0.25z
