3x+7y=35,8x-7y=-35

Solution

3 x + 7 y = 35, 8 x - 7 y = - 35

Solution

x = 0, y = 5

Solution steps

[3 x + 7 y = 35 8 x - 7 y = - 35]

Isolate

x

for

3 x + 7 y = 35 : x = \frac{35 - 7 y}{3}

Substitute

x = \frac{35 - 7 y}{3}

[8 \cdot \frac{35 - 7 y}{3} - 7 y = - 35]

Simplify

[\frac{280 - 77 y}{3} = - 35]

Isolate

y

for

\frac{280 - 77 y}{3} = - 35 : y = 5

For

x = \frac{35 - 7 y}{3}

Substitute

y = 5

x = \frac{35 - 7 \cdot 5}{3}

Simplify

x = 0

The solutions to the system of equations are:

x = 0, y = 5

2 x + 4 y = 4, 3 x + 5 y = 10

2 x + y = 3, x - 5 y = 40

2x+y=35,3x+4y=65

2 x + y = 35, 3 x + 4 y = 65

y = 0, x = 1, x = 2

a + b = 20, a - b = 4
