2x+y=5,x+y=4

Solution

2 x + y = 5, x + y = 4

Solution

x = 1, y = 3

Solution steps

[2 x + y = 5 x + y = 4]

Isolate

x

for

2 x + y = 5 : x = \frac{5 - y}{2}

Substitute

x = \frac{5 - y}{2}

[\frac{5 - y}{2} + y = 4]

Simplify

[\frac{5 + y}{2} = 4]

Isolate

y

for

\frac{5 + y}{2} = 4 : y = 3

For

x = \frac{5 - y}{2}

Substitute

y = 3

x = \frac{5 - 3}{2}

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 3

- 3 x + 2 y = - 11, - x + 3 y = 0

m+11m=4,-5m-3n=10

m + 11 m = 4, - 5 m - 3 n = 10

2 x - y = 2, 4 x - y = 4

7x-5y=15,3x-y=12

7 x - 5 y = 15, 3 x - y = 12

x-y+2=2,x-5y+1=0

x - y + 2 = 2, x - 5 y + 1 = 0
