3x+y=7,4x+3y=6

Solution

3 x + y = 7, 4 x + 3 y = 6

Solution

x = 3, y = - 2

Solution steps

[3 x + y = 7 4 x + 3 y = 6]

Isolate

x

for

3 x + y = 7 : x = \frac{7 - y}{3}

Substitute

x = \frac{7 - y}{3}

[4 \cdot \frac{7 - y}{3} + 3 y = 6]

Simplify

[\frac{28 + 5 y}{3} = 6]

Isolate

y

for

\frac{28 + 5 y}{3} = 6 : y = - 2

For

x = \frac{7 - y}{3}

Substitute

y = - 2

x = \frac{7 - ( - 2 )}{3}

\frac{7 - ( - 2 )}{3} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 2

x-4y=2,0.8-3x+6y=-2.4

x - 4 y = 2, 0.8 - 3 x + 6 y = - 2.4

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

3x+4y=14,5x+2y=14

3 x + 4 y = 14, 5 x + 2 y = 14

g(x)=10x,g(x)=15

g (x) = 10 x, g (x) = 15

(2a-1)*x+3y=5,3x+(b-1)*y=15

(2 a - 1) \cdot x + 3 y = 5, 3 x + (b - 1) \cdot y = 15
