This is the equation of a line. There are an infinite number of solutions. All of the solutions are ordered pairs, (x,y) which represent points on that line.
For example take x=0 and y=7 so (0,7) is on the line.
Now take y=0 and x=7/3 is on the line. So the point (7/3,0) is on the lines.
Those two points are intercepts. If you graph them, you can connect them and you have a graph of the line.
3x+7=37 -7 -7 3x=30 /3 /3 x=10
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
if 3x+5=x+19 then x=7
x = 7 and 2/3
(5, 1)
x=7
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
4x+7-3x = 15 4x-3x = 15-7 x = 8
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
5x+y=-7 3x+y=15 8=D
25-7=18 18/3=6
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
You cannot solve one linear equation in two unknown variables.
3x+4 = 2x-3 3x-2x = -3-4 x = -7
Assuming the question is "solve for x", the answer is x=5
3x + 7y = 14Subtract 3x from each side:7y = -3x + 14Divide each side by 7:y = -3/7 x + 2
