Question

3(х+1)=5(х+1)+4 ..........................​

Answer 1

Пошаговое объяснение:

3х+3=5х+5+4

3х-5х=9-3

-2x=5

X=-2.5

Answer 2

To solve the equation 3(х+1) = 5(х+1) + 4, we need to find the value of х that makes the equation true. We'll start by simplifying the equation step by step:

Step 1: Distribute the numbers outside the parentheses: 3х + 3 = 5х + 5 + 4

Step 2: Combine like terms: 3х + 3 = 5х + 9

Step 3: Get all the х terms on one side and constants on the other side. To do this, we'll subtract 3х from both sides: 3х - 3х + 3 = 5х - 3х + 9

Step 4: Simplify: 3 = 2х + 9

Step 5: Get all the constant terms on one side and the variable term on the other side. To do this, we'll subtract 9 from both sides: 3 - 9 = 2х + 9 - 9

Step 6: Simplify: -6 = 2х

Step 7: Finally, isolate х by dividing both sides by 2: х = -6/2

Step 8: Simplify the fraction: х = -3

So, the solution to the equation is х = -3.
