7x-4y=5,3x-2y=1

Solution

7 x - 4 y = 5, 3 x - 2 y = 1

Solution

x = 3, y = 4

Solution steps

[7 x - 4 y = 5 3 x - 2 y = 1]

Isolate

x

for

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

Substitute

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

[3 \cdot \frac{5 + 4 y}{7} - 2 y = 1]

Simplify

[\frac{15 - 2 y}{7} = 1]

Isolate

y

for

\frac{15 - 2 y}{7} = 1 : y = 4

For

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

Substitute

y = 4

x = \frac{5 + 4 \cdot 4}{7}

\frac{5 + 4 \cdot 4}{7} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 4

Popular Examples

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

w(x,z,y)+x+z=5,y+z=8,x+z=2

w (x, z, y) + x + z = 5, y + z = 8, x + z = 2

2 x - y = 2, 2 x + y = 13

2y-3x=1,-4y+6x=-2

2 y - 3 x = 1, - 4 y + 6 x = - 2

2x+3y=2,(k+2)x+(2k+1)y=2(k-1)

2 x + 3 y = 2, (k + 2) x + (2 k + 1) y = 2 (k - 1)
