3t+4c=65,t+c=18

Solution

3 t + 4 c = 65, t + c = 18

Solution

t = 7, c = 11

Solution steps

[3 t + 4 c = 65 t + c = 18]

Isolate

t

for

3 t + 4 c = 65 : t = \frac{65 - 4 c}{3}

Substitute

t = \frac{65 - 4 c}{3}

[\frac{65 - 4 c}{3} + c = 18]

Simplify

[\frac{65 - c}{3} = 18]

Isolate

c

for

\frac{65 - c}{3} = 18 : c = 11

For

t = \frac{65 - 4 c}{3}

Substitute

c = 11

t = \frac{65 - 4 \cdot 11}{3}

\frac{65 - 4 \cdot 11}{3} = 7

t = 7

The solutions to the system of equations are:

t = 7, c = 11

x + y = 8, 2 x + y = 10

1/((7x))+1/((6y))=3, 1/((2x))-1/((3y))=5

\frac{1}{( 7 x )} + \frac{1}{( 6 y )} = 3, \frac{1}{( 2 x )} - \frac{1}{( 3 y )} = 5

5x+2y=7,7x+6y=-3

5 x + 2 y = 7, 7 x + 6 y = - 3

5x+7y=3,3x+14y=6

5 x + 7 y = 3, 3 x + 14 y = 6

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

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