4x-4=10,5x+2y=14

4 x - 4 = 10, 5 x + 2 y = 14

x = \frac{7}{2}, y = - \frac{7}{4}

Solution steps

[4 x - 4 = 10 5 x + 2 y = 14]

Isolate

x

for

4 x - 4 = 10 : x = \frac{7}{2}

Substitute

x = \frac{7}{2}

[5 \cdot \frac{7}{2} + 2 y = 14]

Simplify

[\frac{35}{2} + 2 y = 14]

Isolate

y

for

\frac{35}{2} + 2 y = 14 : y = - \frac{7}{4}

The solutions to the system of equations are:

x = \frac{7}{2}, y = - \frac{7}{4}

x + y = 13, 70 x + 80 y = 980

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

x + 3 y = 15, 3 x + 6 y = 18

a = 3, c = 3

a = 3, c = 4
