It's a simple linear equation in 'x'. There's only one value of 'x' that can
make it a true statement. Here's how to find it. Watch carefully.
2x + 5 = 4
Subtract 5 from each side of the equation:
2x = -1
Divide each side by 2:
x = -1/2
x equals 4
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x+5=3x+1 -x=-4 x=4
2x-4
k
(4, 5)
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
-4+5-2 = -1
4
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
3x+5=4-2x+6 5x=4-1 5x=3 x=3/5
y=x+5
