Answer:

x=-1

Step-by-step explanation:

4x+7=2x+5

subtract 2x on both sides

4x-2x+7=5

4x-2x=2x

2x+7=5

subtract 7 on both sides

2x=-2

divide both sides by 2

x=-1

hope this helps

Answer:

x = -1

Step-by-step explanation:

4x+7=2x+5

4x - 2x = 5 - 7

2x = -2

x = -2/2

x = -1

Check:

4*-1 + 7 = 2*-1 + 5

-4+7 = -2 + 5 = +3
