x = 4 and y = 7

2x2 + 2x - 8 = 2(x2 + x - 4). This can take any value greater than or equal to -8.5

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

x = 4 and y = 7 which will satisfy both equations

An equation where x equals 3.

2x-y = 4 -y = -2x+4 y = 2x-4 in slope-intercept form

2x squared minus 4

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

6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.

It follows that x - 1 = 2x - 5 as each expression is equal to y. Add 1 to each side: x = 2x - 4 Add 4 to each side: x + 4 = 2x Subtract x from each side: 4 = x y = x - 1 = 3

y + 4 = 2x −1

x= Negative 4

Four minus three equals one. (Or, 4 - 3 = 1.)

4

It equals 8x+12

If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.

X=7

If x=4... then 'y' MUST equal 3 !

it doesn't it equals 4

a=20

No. -4 does not equal -2(1).

y - 4 = 2x +1y = 2x + 5The two intercept points are (0, 5) and (-5/2, 0)

{-1,-2}

Fourteen minus four equals ten...

x=4
