3x+4y=13,4x+3x=15

3 x + 4 y = 13, 4 x + 3 x = 15

x = \frac{15}{7}, y = \frac{23}{14}

Solution steps

[3 x + 4 y = 13 4 x + 3 x = 15]

Isolate

x

for

4 x + 3 x = 15 : x = \frac{15}{7}

Substitute

x = \frac{15}{7}

[3 \cdot \frac{15}{7} + 4 y = 13]

Simplify

[\frac{45}{7} + 4 y = 13]

Isolate

y

for

\frac{45}{7} + 4 y = 13 : y = \frac{23}{14}

The solutions to the system of equations are:

x = \frac{15}{7}, y = \frac{23}{14}

- 4 x + 3 y = - 4, - 8 x + 5 y = 0

x + y = 60, 16 x + 20 y = 1100

- 2 x + y = - 4, 2 x - 3 y = 8

x + 16 - 3 x + 8 y = 23, y = 4

5 x - 21 = 8 y, - 5 y + 10 x = 15
