Answer:
x=7
Step-by-step explanation:
2x-10=4 add 10 to both sides
2x=14 divide both sides by 2
x=7
F(x) = -2 * x + 8
f(-1.8) = -2 * (-1.8) + 8 = 3.6 + 8 = 11.6

We are given with two equations and is asked to determine the solution of the system of linear equation. via elimination, we add the two equations to eliminate 3x, this means y should be equal to 9 and from the first equation, x should also be equal to 9, too
Another basic one
(1/2)^2*1/2*(1/2)^3=
(1/2)^6 =
1\2^6=1/64
if in decimal: 0.015 but i would prefer 1/64 if i was the teacher :)
