3x+2y=21,7x+3y=44

Solution

3 x + 2 y = 21, 7 x + 3 y = 44

Solution

x = 5, y = 3

Solution steps

[3 x + 2 y = 21 7 x + 3 y = 44]

Isolate

x

for

3 x + 2 y = 21 : x = \frac{21 - 2 y}{3}

Substitute

x = \frac{21 - 2 y}{3}

[7 \cdot \frac{21 - 2 y}{3} + 3 y = 44]

Simplify

[\frac{147 - 5 y}{3} = 44]

Isolate

y

for

\frac{147 - 5 y}{3} = 44 : y = 3

For

x = \frac{21 - 2 y}{3}

Substitute

y = 3

x = \frac{21 - 2 \cdot 3}{3}

\frac{21 - 2 \cdot 3}{3} = 5

x = 5

The solutions to the system of equations are:

x = 5, y = 3

Popular Examples

∣ x ∣ - 7 = - 6, x = 1

x + y = 10, x - y = 6

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

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

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

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

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

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