4x+5y=7,10x+3y=8

Solution

4 x + 5 y = 7, 10 x + 3 y = 8

Solution

x = \frac{1}{2}, y = 1

Solution steps

[4 x + 5 y = 7 10 x + 3 y = 8]

Isolate

x

for

4 x + 5 y = 7 : x = \frac{7 - 5 y}{4}

Substitute

x = \frac{7 - 5 y}{4}

[10 \cdot \frac{7 - 5 y}{4} + 3 y = 8]

Simplify

[\frac{- 19 y + 35}{2} = 8]

Isolate

y

for

\frac{- 19 y + 35}{2} = 8 : y = 1

For

x = \frac{7 - 5 y}{4}

Substitute

y = 1

x = \frac{7 - 5 \cdot 1}{4}

\frac{7 - 5 \cdot 1}{4} = \frac{1}{2}

x = \frac{1}{2}

The solutions to the system of equations are:

x = \frac{1}{2}, y = 1

Popular Examples

x - 2 y = 1, 2 x - 3 y = 4

3a+2b=21,3a+10b=21

3 a + 2 b = 21, 3 a + 10 b = 21

3x+7y=11,3x-2y=-7

3 x + 7 y = 11, 3 x - 2 y = - 7

x + 2 = 0, x^{2} = 6

x+3y=11,3(x-1)-5y=-68

x + 3 y = 11, 3 (x - 1) - 5 y = - 68
