Answer:
x = 4.5
Explanation:
6x+7=4x+4y
The first step is to simplify the equation by combining the x terms
Subtract 4x from each side
6x-4x +7 = 4x-4x+4y
2x+7 = 4y
We know the y value is 4
Substitute y=4 into the equation
2x+7 = 4(4)
2x+7 =16
Subtract 7 from each side
2x+7-7 =16-7
2x=9
Divide by 2
2x/2 =9/2
x= 4.5
