2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4

(3, 1)

2x + 3 = 72x = 4x = 2

The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).

{-4,-5}

x = -7

If: 2x+6x-4 = 52 Then: x = 7

2x = -7 - 8y

8x-7 plus 2x equals 6 plus 5x plus 2?

7

x=4

2x+3 = 7 2x = 7-3 2x = 4 x = 2

2x+3-7=0 2x=4 x=2

X=7

no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )

3x+4 = 2x-3 3x-2x = -3-4 x = -7

X=-7

x = 7

If there are no equals you can simplify this by collecting all the x values together and use the addition property of signed numbers. 2x+4x-5x+x=2x; 4+3=7. 2x+7 is the simplified statement.

6x - 8 + 2x - 5 = 7 - 2x ?

x = -2 and y = 3

The answer is (3.5)2 plus (4)2 equals 410.

X=7

Subtract 7 from each side of the equation: 2x = 8 Divide by 2: x = 4
