How do you solve 5x - 4= 2x - 135x4=2x13?

2 Answers

x= -3x=3

Explanation:

Step 1: Subtract 2x2x from both sides of the equation. Thus, you have

3x-4=-133x4=13

Step 2: Add 44 to both sides. You now have

3x= -93x=9

Step 3: Multiply each side by 1/313. Thus, you are left with

x= -3x=3

x=-3x=3

Explanation:

We know that if we perform the same operation on both sides of the equation, we still get an equality. We start with the equation:

5x-4=2x-135x4=2x13

We now try to isolate the xx's. That is, we want to put all the xx's on one side:

5x-4-2x=2x-13-2x5x42x=2x132x

Combine like terms:

3x-4=-133x4=13

We now add 44 to both sides:

3x-4+4=-13+43x4+4=13+4

3x=-93x=9

Finally, we divide both sides by 33:

(3x)/3=(-9)/33x3=93

x=-3x=3
