4x+3y=84,2x+5y=70

Solution

4 x + 3 y = 84, 2 x + 5 y = 70

Solution

x = 15, y = 8

Solution steps

[4 x + 3 y = 84 2 x + 5 y = 70]

Isolate

x

for

4 x + 3 y = 84 : x = \frac{84 - 3 y}{4}

Substitute

x = \frac{84 - 3 y}{4}

[2 \cdot \frac{84 - 3 y}{4} + 5 y = 70]

Simplify

[\frac{84 + 7 y}{2} = 70]

Isolate

y

for

\frac{84 + 7 y}{2} = 70 : y = 8

For

x = \frac{84 - 3 y}{4}

Substitute

y = 8

x = \frac{84 - 3 \cdot 8}{4}

\frac{84 - 3 \cdot 8}{4} = 15

x = 15

The solutions to the system of equations are:

x = 15, y = 8

Popular Examples

5 x + 3 y = 8, 3 x + y = 2

3x+5y=40,2x+4y=25

3 x + 5 y = 40, 2 x + 4 y = 25

3x-y=17,2x+3y=-4

3 x - y = 17, 2 x + 3 y = - 4

((x+y))/((x-y))=-7,((x+y+1))/((x+y-1))= 3/4

\frac{( x + y )}{( x - y )} = - 7, \frac{( x + y + 1 )}{( x + y - 1 )} = \frac{3}{4}

1x-2y=5,2x+3y=24

1 x - 2 y = 5, 2 x + 3 y = 24
