Answer:

X= -6

Step-by-step explanation:

7x+6−5x+10=4

Step 1: Simplify both sides of the equation.

7x+6−5x+10=4

7x+6+−5x+10=4

(7x+−5x)+(6+10)=4(Combine Like Terms)

2x+16=4

2x+16=4

Step 2: Subtract 16 from both sides.

2x+16−16=4−16

2x=−12

Step 3: Divide both sides by 2.

2x/2   =  −12 /2

x=−6
