Answer:

x=7/10

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+5=12−7x

Step 1: Simplify both sides of the equation.

3x+5=12−7x

3x+5=12+−7x

3x+5=−7x+12

Step 2: Add 7x to both sides.

3x+5+7x=−7x+12+7x

10x+5=12

Step 3: Subtract 5 from both sides.

10x+5−5=12−5

10x=7

Step 4: Divide both sides by 10.

10x10=7/10

x=7/10
