s-7t+42=0,s-3t=6

Solution

s - 7 t + 42 = 0, s - 3 t = 6

Solution

s = 42, t = 12

Solution steps

[s - 7 t + 42 = 0 s - 3 t = 6]

Isolate

s

for

s - 7 t + 42 = 0 : s = 7 t - 42

Substitute

s = 7 t - 42

[7 t - 42 - 3 t = 6]

Simplify

[4 t - 42 = 6]

Isolate

t

for

4 t - 42 = 6 : t = 12

For

s = 7 t - 42

Substitute

t = 12

s = 7 \cdot 12 - 42

Simplify

s = 42

The solutions to the system of equations are:

s = 42, t = 12

x + y = 5, x - y = 1

4x+3y=17,6x+5y=27

4 x + 3 y = 17, 6 x + 5 y = 27

2x-y+3z=13,x+2y+z=12,3x-y+z=7

2 x - y + 3 z = 13, x + 2 y + z = 12, 3 x - y + z = 7

9x+11y=-14,6x-5y=-34

9 x + 11 y = - 14, 6 x - 5 y = - 34

x + y = 3, 2 x - y = 0
