Answer 3

Solution to the Equations:

а) Let's solve the equation: (3х + 5х) * 18 = 144

To solve this equation, we need to simplify the expression on the left side and then solve for x.

First, let's simplify the expression: (3х + 5х) * 18 = 144 Combining like terms, we get: 8х * 18 = 144 Multiplying 8 and 18, we have: 144х = 144 Now, we can solve for x by dividing both sides of the equation by 144: x = 1

Therefore, the solution to the equation (3х + 5х) * 18 = 144 is x = 1.

б) Now, let's solve the equation: (7у - 3у) / 8 = 17

To solve this equation, we need to simplify the expression on the left side and then solve for у.

First, let's simplify the expression: (7у - 3у) / 8 = 17 Combining like terms, we get: 4у / 8 = 17 Simplifying further, we have: у / 2 = 17 To isolate у, we multiply both sides of the equation by 2: у = 34

Therefore, the solution to the equation (7у - 3у) / 8 = 17 is у = 34.

в) Let's solve the equation: (6а + а) / 13 = 14

To solve this equation, we need to simplify the expression on the left side and then solve for а.

First, let's simplify the expression: (6а + а) / 13 = 14 Combining like terms, we get: 7а / 13 = 14 To isolate а, we multiply both sides of the equation by 13: 7а = 14 * 13 Simplifying further, we have: 7а = 182 Now, we can solve for а by dividing both sides of the equation by 7: а = 26

Therefore, the solution to the equation (6а + а) / 13 = 14 is а = 26.

г) Finally, let's solve the equation: 48 / (9b - b) = 2

To solve this equation, we need to simplify the expression on the left side and then solve for b.

First, let's simplify the expression: 48 / (9b - b) = 2 Combining like terms, we get: 48 / 8b = 2 Simplifying further, we have: 6 / b = 2 To isolate b, we multiply both sides of the equation by b: 6 = 2b Now, we can solve for b by dividing both sides of the equation by 2: b = 3

Therefore, the solution to the equation 48 / (9b - b) = 2 is b = 3.
