Answer:
x=1 is the solution of the equation 2x+4=10−4x
Step-by-step explanation:
The graphs of f(x)=2x+4 and g(x)=10−4x intersect at (1, 6)
2x +4 = 10 - 4x
We need to solve for x by combining like terms
Add 4x on both sides
6x + 4= 10
Now subtract 4 on both sides
6x = 6
divide both sides by 6
x= 1
x=1 is the solution of the equation 2x+4=10−4x
