Answer:
x=0.9
Step-by-step explanation:
4x+9
7
3
=
3x
0.5
Step 1: Cross-multiply.
(4x+9)*(0.5)=3x*(
)
2x+4.5=7x
Step 2: Subtract 7x from both sides.
2x+4.5−7x=7x−7x
−5x+4.5=0
Step 3: Subtract 4.5 from both sides.
−5x+4.5−4.5=0−4.5
−5x=−4.5
Step 4: Divide both sides by -5.
−5x
−5
−4.5
-8
3+8+8-2=17
7+4+5+1=17
10+12+3+x=17
x=17-25
=-8
