2x+3=-2x+3
4x=0
x=0
substituting
y=3
so the soln.set(0,3)

in the past I provide the answer, you ought to understand the rhyme and clarification for the substitution technique. you're provided that y=2x+3 on your 2nd equation, plug in(replace) what you're given like so: 5x -2(2x+3) = -5 5x - 4x -6= -5 x=a million Now pass back on your first equation and remedy for y: y=2x +3 y=2(a million) +3 y = 5 answer: (a million,5)

y=2x+3 y=-2x+3
y is equal to both, so
2x+3=-2x+3
2x+3-3=-2x+3-3
2x=-2x
2x+2x=-2x+2x
4x=0
x=0
then substitute 0 for x in the original equations
y=2(0)+3 y=-2(0)+3
y=0+3 y=0+3
y=3
so your solution is x=0 y=3

y=2x+3
y=-2x+3
This is just a matter of substitution when u assigned x and y to any number.
For example in the first equation y=2x+3
If Y = 1 then find x
1=2x+3
x=-1
Second equation y=-2x+3
If y=1 then find x
1=-2x+3
x=1
This is also the same thing when u assigned x and find y.

Simply solve the two linear equations by elimination method. If u add up these two equations, you get y = 3, which will lead to x = 0

add these to equations
so
2y=6
y=3
for
x substitute y in one of the equation
so in eq 1
3=2x+3
0=2x (adding -3 to both sides)
x=0
ANS IS X=0 AND Y=3
"SO AT POINT HAVING CO ORDINATES (0,3)
THESE TWO LINES WILL MEET"

Add the two equations.
y=2x+3
+ y=-2x+3
-----------------
2y= 6
y=3
x=0.

I think thats an x and y intercept thing. i just had a test on that
you do
y=0
so 0=2x+3
x=-3
x=0 now
y=2 x 0 +3
y=3

y = 2x + 3
y = -2x + 3
2y = 6
y = 3
x = 0
