x-4=4,y+83x-6+2y=20

x - 4 = 4, y + 83 x - 6 + 2 y = 20

x = 8, y = - \frac{638}{3}

Solution steps

[x - 4 = 4 y + 83 x - 6 + 2 y = 20]

Isolate

x

for

x - 4 = 4 : x = 8

Substitute

x = 8

[y + 83 \cdot 8 - 6 + 2 y = 20]

Simplify

[3 y + 658 = 20]

Isolate

y

for

3 y + 658 = 20 : y = - \frac{638}{3}

The solutions to the system of equations are:

x = 8, y = - \frac{638}{3}

m + c = 28, 2 m + 4 c = 88

6 x + 3 y = 18, 3 x + 4 y = 15

0.4 x + 0.3 y = 1.7, 0.7 x - 0.2 y = 0.8

2 (x - 4) = 9 y + 2, x - 6 y = 0

6 x + 7 y = 9, 8 x + 9 y = 11
