Question

Can I plz get the mathematical reasoning and language explanation can someone please give me with the answer I'm very stuck on it, something that would give me a 4 thank you I appreciate it

Answer 1

Simplify both sides of the equation(-1.3x+-7.4x)+(7)=(1.5x+-6x)+(9)

-10.5x+7=-4.5x+9

Add 4.5 to both sides
-6x+7=9

Subtract 7 from both sides
-6x=2

Divide both sides by -6

x= -1/3
