Question

Solve: x+y=3 2x+3y=7I need this answer fast​

Answer 1

2x➕2y=6
2x➕2y ➖（2x➕3y）=6➖7
-y=-1
y=1
x=3➖1=2

Answer 2

Answer:

If you were to make these two equations in slope intercept form, here's what it would be like;

First the formula for slope intercept form is, y = mx + b

where m represents the slope and b is the y intercept(where the line meets the y axis)

First equation;

x + y = 3

we need to isolate y so we subtract x from both sides

-x       -x

y = -x + 3 (we put the -x before the 3 because that's how the formula is formatted)

Second equation;

2x + 3y = 7

Isolate y by subtracting 2x away from both sides

-2x       -2x

3y = -2x + 7, y is not fully isolated because it has a coefficient and it's supposed to be just y, so we divide both sides by 3:

/3       /3

y = -2/3x + 2 1/3
