what value of x satisfies the equation 5x+1.5=7? explain your answer.

x=1.1 satisfies the equation because 7−1.5=5.5 and 5.55=1.1.

x=1.1 satisfies the equation because 7−1.5=5.5 and 1.1⋅5=5.5.

x=-1.1 satisfies the equation because 1.5−7=-5.5 and -1.1⋅5=-5.5.

x=-1.1 satisfies the equation because 1.5−7=-5.5 and -5.55=-1.1.


what value of x satisfies the equation 3x+1.2=3? explain your answer.

x=-0.6 satisfies the equation because 1.2−3=-1.8 and -0.6⋅3=-1.8.

x=0.6 satisfies the equation because 3−1.2=1.8 and 0.6⋅3=1.8.

x=-0.6 satisfies the equation because 1.2−3=-1.8 and -1.8/3=-0.6.

x=0.6 satisfies the equation because 3−1.2=1.8 and 1.8/3=0.6.
