Answer z = 6 Explanation Given: 15 z = 30 + 10 z Concept Used: In an equation, like terms are added or subtracted with each other. Any value if added, subtracted, multiplied or divided on the left hand side of the equation, then it should also be added or subtracted on right hand side so that the equation is balanced. Calculation: To simplify the equation 15 z = 30 + 10 z First subtract each side of the equation by 10 z as, 15 z − 10 z = 30 + 10 z − 10 z ⇒ 5 z = 30 Now, divide both sides by 5 as, 5 z 5 = 30 5 ⇒ z = 6 Thus, the simplified equation becomes z = 6

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

To simplify the equation

15z=30+10z

Expert Solution & Answer

Answer to Problem 8MRE

z=6

Explanation of Solution

Given:

15z=30+10z

Concept Used:

In an equation, like terms are added or subtracted with each other.
Any value if added, subtracted, multiplied or divided on the left hand side of the equation, then it should also be added or subtracted on right hand side so that the equation is balanced.

Calculation:

To simplify the equation

15z=30+10z

First subtract each side of the equation by 10z as,

15z−10z=30+10z−10z⇒5z=30

Now, divide both sides by 5 as,

5z5=305⇒z=6

Thus, the simplified equation becomes

z=6
