Question

Solve the system of linear equations by substitution WILL GIVE MEDAL AND FAN!
y = 5x + 6

can anyone provide an example of how to do it with the same set-up as my question above? something like....

y = 3x + 4 or something?

Answer 1

i don't see a system of equations, i only see 1 equation
y=5x+6
and yes.

Answer 2

by substitution means you need to put y=.... from one equation into other equation.

Answer 3

example, y= ax+b, y=cx+d
then ax+b = cx+d
and you can find 'x' from here.

Answer 4

yes,

Answer 5

5x + 6 = -2x - 8
add 2x on both sides,
subtract 6 from both sides...
in short, try to find 'x'

Answer 6

where did 'x' go ?
add "2x" on both sides.

Answer 7

yes, now simplify that.
