x=7.5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2.45+5.5x−4.3x=1.3+0.7x
−2.45+5.5x+−4.3x=1.3+0.7x
Step 2: Combine Like Terms
(5.5x+−4.3x)+(−2.45)=0.7x+1.3
1.2x+−2.45=0.7x+1.3
1.2x−2.45=0.7x+1.3
Step 3: Subtract 0.7x from both sides.
1.2x−2.45−0.7x=0.7x+1.3−0.7x
0.5x−2.45=1.3
Step 4: Add 2.45 to both sides.
0.5x−2.45+2.45=1.3+2.45
0.5x=3.75
Step 5: Divide both sides by 0.5.
0.5x/0.5=3.75/0.5
so
x = 7.5
