Question

If f(x) = -3x + 4 and g(x) = 2, solve for the value of x for

which f(x) = g(x) is true.
Ya

Answer 1

f(x) = g(x)

-3x+4 = g(x) ... f(x) replaced with -3x+4

-3x+4 = 2 .... g(x) replaced with 2

-3x+4-4 = 2-4 .... subtract 4 from both sides

-3x = -2

-3x/(-3) = -2/(-3) .... divide both sides by -3

x = 2/3

Answer: 2/3
