x+2y=3,x-3y=13

Solution

x + 2 y = 3, x - 3 y = 13

Solution

x = 7, y = - 2

Solution steps

[x + 2 y = 3 x - 3 y = 13]

Isolate

x

for

x + 2 y = 3 : x = 3 - 2 y

Substitute

x = 3 - 2 y

[3 - 2 y - 3 y = 13]

Simplify

[3 - 5 y = 13]

Isolate

y

for

3 - 5 y = 13 : y = - 2

For

x = 3 - 2 y

Substitute

y = - 2

x = 3 - 2 (- 2)

3 - 2 (- 2) = 7

x = 7

The solutions to the system of equations are:

x = 7, y = - 2

5x+4y=4,x-20=20y

5 x + 4 y = 4, x - 20 = 20 y

x+2y=10,4x-2y=5

x + 2 y = 10, 4 x - 2 y = 5

5a^5=62,5n=3,a^4=12

5 a^{5} = 62, 5 n = 3, a^{4} = 12

2x+y=-6,3x-2y=4

2 x + y = - 6, 3 x - 2 y = 4

3x+5y=34,2x-y=1

3 x + 5 y = 34, 2 x - y = 1
