a+2b=3,2a+b=0

Solution

a + 2 b = 3, 2 a + b = 0

Solution

a = - 1, b = 2

Solution steps

[a + 2 b = 3 2 a + b = 0]

Isolate

a

for

a + 2 b = 3 : a = 3 - 2 b

Substitute

a = 3 - 2 b

[2 (3 - 2 b) + b = 0]

Simplify

[6 - 3 b = 0]

Isolate

b

for

6 - 3 b = 0 : b = 2

For

a = 3 - 2 b

Substitute

b = 2

a = 3 - 2 \cdot 2

Simplify

a = - 1

The solutions to the system of equations are:

a = - 1, b = 2

2 x + 5 y - 2 = 0, e^{3} x + 5 y - 28 = 0

x-65x^3y=-1,y=4

x - 65 x^{3} y = - 1, y = 4

(x)=4,x-12f(x)-1(x)=x

(x) = 4, x - 12 f (x) - 1 (x) = x
