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

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

x = \frac{2}{3}, y = \frac{8}{3}

Solution steps

[3 x + 4 = 6 2 x - 2 y = - 4]

Isolate

x

for

3 x + 4 = 6 : x = \frac{2}{3}

Substitute

x = \frac{2}{3}

[2 \cdot \frac{2}{3} - 2 y = - 4]

Simplify

[\frac{4}{3} - 2 y = - 4]

Isolate

y

for

\frac{4}{3} - 2 y = - 4 : y = \frac{8}{3}

The solutions to the system of equations are:

x = \frac{2}{3}, y = \frac{8}{3}

x - 2 y = 9, 3 x + y = 41

7 x + 8 = 9, - 5 x = 17

- 6 x + 6 y = 6, - x + y = 1

9 b = 200, a = 11

3 x - 4 y - 17 = 4, x + 5 y = 21
