Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

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.

Question

Chapter 1.3, Problem 15E

To determine

To solve and check: the solution of the given equation.

Expert Solution & Answer

Answer to Problem 15E

The required result is y=−12

Explanation of Solution

Given:

5(1+2m)=12(8+20m)

Calculation:

Solve:

10(2y+2)−y=2(8y−8) Given

20y+20−y=16y−16 Use Distributive Property

19y+20=16y−16 Combine like terms

19y+20−20=16y−16−20 Subtract both sides by 20

19y−16y=16y−16y−36 Subtract both sides by 16y

3y3=−363 Divide both sides by 3

y=−12 Simplify

Check:

10(2y+2)−y=2(8y−8) Given

10(2(−12)+2)−(−12)=2(8(−12)−8) Substitute

10(−24+2)+12=2(−96−8) Simplify

10(−22)+12=2(−104) Simplify

−220+12=−208 Simplify

−208=°−208 Simplify

y=−12

Therefore, y=−12

Conclusion:

Therefore, y=−12
