2(2x-4)+y=3,-x+2y=4

Solution

2 (2 x - 4) + y = 3, - x + 2 y = 4

Solution

x = 2, y = 3

Solution steps

[2 (2 x - 4) + y = 3 - x + 2 y = 4]

Isolate

x

for

2 (2 x - 4) + y = 3 : x = \frac{- y + 11}{4}

Substitute

x = \frac{- y + 11}{4}

[- \frac{- y + 11}{4} + 2 y = 4]

Simplify

[\frac{9 y - 11}{4} = 4]

Isolate

y

for

\frac{9 y - 11}{4} = 4 : y = 3

For

x = \frac{- y + 11}{4}

Substitute

y = 3

x = \frac{- 3 + 11}{4}

\frac{- 3 + 11}{4} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 3

b*m+n+r=3,2m-n+r=2,3m+3n-r=5

b \cdot m + n + r = 3, 2 m - n + r = 2, 3 m + 3 n - r = 5

3m-2n=-2,6m+4n=-20

3 m - 2 n = - 2, 6 m + 4 n = - 20

2x+3y=10,3x-y=4

2 x + 3 y = 10, 3 x - y = 4

y = x + 3, y = 2 x + 5
