PLEASE ANSWER ASAP!!! Solve for X. 15=7x+3-5x X=_(simplify your answer)
dedylja [7]

Answer:

X=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15=7x+3−5x

15=7x+3+−5x

15=(7x+−5x)+(3)(Combine Like Terms)

15=2x+3

15=2x+3

Step 2: Flip the equation.

2x+3=15

Step 3: Subtract 3 from both sides.

2x+3−3=15−3

2x=12

Step 4: Divide both sides by 2.

2x2=122

x=6

Answer:

x=6
